Working out order from a rate table - tricky example

Walkthrough of one of those pesky orders questions where you can't keep a concentration constant

[@shreyasingh118]

Thankyou you so much..it was difficult but now ..its easy 😭❤️❤️

[@v.ciziri]

Thank you sir this was so much easier than what I thought ❤

[@Rubinaa_27]

Can you please explain again how you got order number 1 for the last question?

[@chocken4867]

You made it a little confusing at the end.

[@dfszf4743]

did he?

[@mentor1324]

You are the best sir

[@star123_12]

what would you do if 0.36 and 0.72 were inverted so you had to divide by 2 instead of x2

[@p.thansheehamajeed5461]

VERy nicely explained

[@rawendbenaribi]

I still didn’t understand why is should be 1st order !! ?

[@TerrenciaVlogs]

thank you! I was doing a past paper and this one was pretty difficult for me, but in under 3 minutes you cleared it up. Thank you!

[@MaChemGuy]

Glad it helped!

[@parvathisunil7037]

thanks for the video , can you pls solve questions where in the table all values are different

[@MaChemGuy]

Already made

THANK YOUUUU

Hello one quick question. Do you need to learn about optical isomerism in making medicine? I’ve done loads of old past papers and they always come up and don’t know if I actually need to learn it or not. Thanks

[@MaChemGuy]

Razor. Not on the new OCR spec

[@mccree8851]

why does no one else use this method, way easier to remember than interim method

[@chasladhar1774]

Good exam question

[@hoodiehoodie4419]

Thank you for this, it really cleared things up. But why is it first order, would you be able to explain?

[@MaChemGuy]

In experiments 2&3 the overall rate increases by 8. The conc of A doubles (so that leads to a 4 x increase in the rate) and therefore order for B must be 1 so that 4 x 2 gives the 8

[@hoodiehoodie4419]

@@MaChemGuy Okay thanks a lot

[@jc.88132]

omggggg thxxxx

[@aliyah8701]

wait how come you have the base numbers as 2 for A and B?

[@TheRealDanielTV]

hes using the last row

[@TheRealDanielTV]

thanks machemguy .

[@RuhabDabeer]

Oh but what if u have three stuff
Like A B and C

[@MaChemGuy]

Ruhab Dabeer Same principle

[@RuhabDabeer]

@@MaChemGuy oh thanks a bunch
Best Chem teacher In RUclips

[@RuhabDabeer]

@@MaChemGuy But what if you don't know the what the other powers of B and C but only knew A's Powers
Then how would you work out B and C
And what if A and B or B and C or A and C goes up by different numbers then is it a problem?

[@Nbeatschilliheats]

Poorly explained

[@MaChemGuy]

Thanks for the view 👌

[@hprivate9114]

BOO you, not really was perfectly understandable :)

[@H1-NMR]

How stupid why watch it if your that arrogant about rates go and get a life and stop hate bombing

[@H1-NMR]

@@MaChemGuyvery well explained 🎉
