Working out order from rate tables (more difficult example)

This tough nut to crack involves a rate table where concentration of reactants change on more than one reagent making it less obvious what effect that reagent has on rate. Take a look at this video to find out what I mean exactly. Hope this method will help!

[@rubycurrie8682]

Broski it’s 2023 and this video is the most helpful. You’re making a difference through the years. Thank you so much

[@freesoulvlogs6611]

2024

[@Blaze-ls3zw]

Brilliantly explained. I shall use your "interim rate" technique and dividing the two numbers from now. That makes it much easier.

[@AlleryChemistry]

Brilliant. Yes, this is the toughest type you will get so I'm pleased you have understood it.

[@junaidayoub2470]

god bless your soul and bald head

[@AlleryChemistry]

Ha! Thanks!

[@danitajaundoo5459]

Junaid Ayoub I agree

[@shellybelly1071]

These 'interims' might have saved my whole A level. Thank you so much- the explanation was both detailed and easy to follow!

[@AlleryChemistry]

You're very welcome!

[@xXukrainianizationXx]

Thanks for the clear explanation Chris! I find rate tables a breeze now! It would be awesome to see more videos on difficult questions like these in the future.

[@AlleryChemistry]

+Taras Mogetich Thanks very much. Yes I am looking to balance standard demand content with high demand to appeal to a wider audience. Keep up to date by following me on twitter @allerytutors

[@straxsa]

I'm hoping this type of question comes up in the exam this summer. You made it look so easy omg

[@AlleryChemistry]

You're very welcome!

[@mahnoorsadia3874]

I looked through so many videos to find one that explain like you did so thank you so much really helpful

[@AlleryChemistry]

Glad it helped!

[@dylanr5259]

You are my bloody saviour, literally racking my brain with this for no reason.

[@lorettakurtz1731]

Legend. Less than two days before the exam I finally understand how to do problems like these. THankyou!

[@shona3180]

best video i have ever seen, thank you soo much! i have been struggling for weeks with this.

[@AlleryChemistry]

You're welcome! So pleased it helped. Please share the vid, the more people it helps the better!

[@harmabebae5500]

[@ameidle]

I've been struggling so much with this topic, I've finally understood, thanks a lot!

[@wunmi.e6]

I still am I hate it!! 2 more months before a levels

[@FatimaKhan-on4bj]

Thank you so much! This was very helpful for me because I didn't understand how to do these but I do now! Hope this comes up in my exam

[@AlleryChemistry]

No problem at all

[@afsahzeenath2638]

Thank you so much,
you deserve way more recognition for these videos

[@gracebickerstaff5810]

makes so much more sense now. thank you
explain so much better than my teacher

[@iramluvsonedirection]

This video makes me love these sort of questions now because you've made it so clear and concise !! I didn't understand them before but now I do, thanks once again!!!

[@AlleryChemistry]

+iram khan Brilliant! Pleased it has helped you! Share the vid, the more people they help, the better.

[@z_loro4126]

Thank you so much, I wasn’t here for my chemistry lesson when my teacher went over this so I didn’t get it but now I do. May God bless your soul!!

[@shahnoor7941]

best chemistry teacher on youtube

[@JamesBoothby15]

Very smart way to communicate this problem, very good explanation.

[@leannemrayat7227]

Thank you so so much sir !! This is a concept I struggled with a lot and it stressed me out but your videos have been extremely helpful. Thank you sooo much :)

[@nic741]

I just encountered a question similar to this. Thank you so much for your videos, without them we would be lost.

[@thegawjus22]

Is there a video were you talk about half life? and I will deffo be looking forward to the Arrhenius equation vid! Will you be uploading it any time soon? I'm asking because I have a test on Wednesday and I'm struggling with it. Thank you so much for this!!

[@AlleryChemistry]

Hi. I don't have anything on half life directly so it will now go on my to do list. It may be difficult to get it done by Wednesday as I am working so much lately. If you have something specific just get in touch via facebook or twitter - search @allerytutors and send a private message. Would be good to help you understand better.

[@AlleryChemistry]

Also just decided to film Arrhenius equation today. Will be uploaded tonight! Hope it helps you!

[@thegawjus22]

Thank you, I'll be looking forward to that video! I don't have FB but I have twitter, I can't Direct Message you on it unless you either follow me or you change your twitter settings to receive a DM from anyone

[@AlleryChemistry]

I have changed settings so you can now DM.

[@missmuslimmah9500]

This is amazing! The interim rate is a massive help!! Thank you so much

[@randomtv7920]

damn man u teach more than my teacher

[@Sillylifehacks]

You can call me a Chris guy caz since day 1 his videos have been helpful

[@hopeshineseternal]

Thank you so much this helped a lot especially at that interim rate part

[@zeyosenpai958]

wow. this saved me. i understand completely now.

[@noorlowtun1703]

Still helping 6 yrs later 👌💥

[@AlleryChemistry]

It never ages! 😀

[@doubitn7969]

You saved my life (my chem). Thank you so much.

[@dno.16]

this had me stressing but now i understand thank you sm

[@AlleryChemistry]

You're very welcome. 😀

[@swiftietay99]

THANK YOUU I was doing all sorts of algebra that was hit and miss getting them right! 😂 sorted 👌

[@AlleryChemistry]

You're welcome! A use for algebra, I but you never thought anyone would say that to you ay!

[@ezrieprideaux3403]

Thank you so much for explaining this in a way that actually makes sense

[@abusuleymantariq2137]

God bless you for this. You've really helped me. 🙌

[@AlleryChemistry]

You are so welcome

[@fzka_]

Oh im grateful to find this video! Thank you sir!

[@AlleryChemistry]

Welcome!

[@anonymousyouth7479]

Hi there, wouldn't C be First order as you have divided by 2.3 on both sides so wouldn't it be first order?

[@hrperformance]

Thank you so much for this example mate!! Very well explained, thank you!

[@edenschannel101]

Exam in 3 days and this is genuinely the first time I've understood rate equations 💀

[@optimusprimo]

AWESOME! question @6:28 , when he says find the DIFFERENCE between interim and intitial, is that intended to be the QUOTIENT? also is it always the larger quotient to smaller? or interim quotient to initial? THANK YOU!

[@puddleduck1405]

THANK YOU I FINALLY UNDERSTAND IT GOD BLESS YOU

[@jameel-i]

Thanks man, explained it well now i fully get it

[@justlaur2648]

This may be a silly question but what if the numbers in the table haven’t quite doubled but are close enough? Would you still round it and say “yeah that’s doubled” ?

[@tymoorhyder9399]

when u found for c y didnt u use interm rate?

[@Annonymous284]

Thank you for the amazing video!

[@dearlantsov]

5:22 what would we do if B was 2nd order instead of 1st order??

[@0ello0]

Thank you so much hero
I was getting so frustrated 🙏

[@ibraking_1939]

i was struggling with this so much. thank u s much

[@pulriopulrio6269]

what if the order of B was 2 instead? would we multiply the factor by 2 for interim rate?

[@Rin-ot7ww]

Thank you so so much, now I've finally got this!

[@silenttreatment4459]

Thanks! You are an amazing teacher!

[@muxilera]

That was so helpful - thank you so much!

[@AlleryChemistry]

You're welcome 😊

[@L1_scann]

cheers chris

[@johnwallace1950]

what happens if say (A) is divided by 2 but the rate is times 2 then would this cancel to 0 order?

[@kiantailor2612]

Thanks so much

[@reubenconstantine2685]

Could someone explain how a reactant can be zero order? Like surely at some point the concentration has to have some effect?

[@flowerdaniel305]

How did you work out the interim rate? Thanks

[@aisosaosifo2469]

can you do some examples on the Arrhenius equation?

[@AlleryChemistry]

Yes. This is on my to do list! This has been added to exam boards recently so will defo be doing it.

[@aisosaosifo2469]

thank you :D

[@h9.k]

what if the rate is the same for both a and b....what would the interim rate be then?

[@favianabarca630]

Thank you.

[@AlleryChemistry]

You're welcome!

[@trick__star]

Thank you very much ,it was very usefull

[@alyfenech1000]

Welcome to the channel (a well established one now 😀)

[@tfh5575]

god why don't I get this? :( The east example was too easy for my book, and this one is a bit harder than my book. I'm so lost ugh

[@tfh5575]

it just clicked thanks lol

[@jessbradford4127]

i love you

[@DoctorGamerr]

How the f*** did he get 6.3x10^-3 as his interim rate at 5:55 ????

[@mohammednaqi5166]

قرعتك تلمع

Thank you seth rogen
