Generally, this is an easy concept. However, what I didn't know until years after I took general chemistry is the fact that liquids and solids are not included in the equilibrium expression. I've gotten a question incorrect on an exam, and now I cannot forget it. Ingrain this fact into your memory guys!
This is not entirely correct. In a heterogenous system where the substances are in more than one phase, solids and liquids are not included in the equilibrium expression. In a homogenous system, where all substances are in the same phase, solids and liquids are included because the relative proportions are important.
@@dorsia6938 thank you for this!! and btw the term 'relative proportion' how much of one thing you have relative to something else. where the 'one thing'= reactant, 'something else' = product.. right?
Professor Organic Chemistry Tutor, thank you for showing How to write the Equilibrium expression for a Chemical Reaction in AP/General Chemistry. The concept is simple to follow and understand provided that students/nonstudents realize that liquids and solids are not included in the equilibrium constant expression. This is an error free video/lecture on RUclips TV with the Organic Chemistry Tutor.
Sulphur trioxide decomposes at high temperature in a sealed container: 2S03(g) ⇌ 2SO2(g)+ O2(g) Initially the vessel is charged at 1000 K with S03(g) at a concentration of 6.09 x 10-3 M. At equilibrium, the concentration of S03(g) was 2.44 x 10-3 M. Calculate the value of Kc Can someone pls help me out with this
Might be a bit late, but basically a balanced equation is when both sides have an equal amount of each element. And basically you check that to see if it's balanced or not. *Note, just in case: if an element doesn't have number to it's right, that means there's just 1 of it. Ex: NH3 is just N1H3 For example, the first example shown in the video is: N2 + H2 = NH3 However, this equation is not balanced as the left side contains 2 Nitrogen and 2 Hydrogen, while the right only contains 1 Nitrogen and 3 Hydrogen. So, in order to balance them, or make the amounts of elements equal on both sides, this happens: 1(N2) + 3(H2) = 2(NH3) --> N2 + H6 = N2H6 or basically: N2 + H6 = N2 + H6 *Second note: the 2 on the right gets distributed to both N and H. This whole process of balancing is basically trying to find the least common "multiple" between both sides. I hope this helps, and if you've already figured it out by now that's equally as great. I also wrote this reply on desktop, so it might look weird if you're viewing it through mobile.

You are one of the main reasons my AP Chem is above 95% rn. Thank you so much for explaining everything so simply yet efficiently.

For heterogeneous reactions thats is

I'm currently taking general chemistry... finally took the plunge to go back to school and get my bachelor's degree 🤓
you make chemistry not so scary
I did not understand in 40 min class and got confused but you understood that in first 2 min
Thanks alot sir

I'm taking General Chemistry in an accelerated program. I use my textbook as an itinerary and this RUclips channel to do my learning.
I literally just learned this in chem today lol. Good review
I literally have a test tomorrow about this, and I am only learning about it now lol
@@srirachasoldier3417same here haha
This dude is always good with his explanations
Thank you! This breaks down the essence of the topic while giving you all of the details you need to solve problems!
Very useful simply explained
Thank you
Thanks a lot this was really helpful
Watching this now because I have a Chemistry exam tomorrow 😩
It was very useful thankyou sir
You made it so easy
Why we take the ratio of products to reactants not by the ratio of reactants to products?
Thank you for clarification 💗
you're my hero
thank you so much this helped a lot :)
Wowwwwwwww proud of you
I wish I would subscribe him 2 times
Thank u so so much!!
Thank you!!!!
Can I submit questions to you? LORD knows I struggle a bit in this... like... I kinda like chemistry... I just need more help to fully grasp it.
Thanks a lot.
U literally saved me
Thank you so much ❤️
Thanks
Thank you bro
nice video but can you raise your volume if u have some time
Thank you ❤️❤️❤️
Thank you for this♥️
It means we will put product upside and reacrants below....

You the best
Amazing thank you so much
Thx for video
Didn't know it was this easy😹tnx
Is Kc used for solid & liquid phase??
the explantion was good but i got stuck on where did he get the coefficients?? the 1,1,2 & 1,3,2
@Yu Katsuragii nah i think it depends if it was given as for my problem there were no coefs sooo i solved w/o coefs coz there was no indicated..🙂🙂
thank u..
you are a genius! thank you!
When your chem teacher does everything else EXCEPT for teaching so you gotta re-teach yourself everything he “teaches” 🙄🙄
Thanks.
thx
Just wow. Mas magaling pa magturo to
Yes
Sir if we consider x mole of N2 than want be

Can someone pls help me out with this
man you took an L. 7 months and nothing. Sorry
You my boy blue !
My teacher is a newbie to this chemistry subject so we have a hard life
I love you
who else is watching this at 1.5x speed
Legends are watching in nov and dec
❤❤❤❤❤❤
Dont why techers make it uncessesary tough
HOW DO YOU KNOW WHEN THE REACTION IS BALANCED OR NOT HELP😭
