How come the answer i got from when you plug in the values for [NO}^2, [N2], [O2]. looks like this (7.7 X 10^-6)^2 / (0.052)(0.025) = 5.929 X 10 ^-11 / (0.052)(0.025)= 2.850 X 10^-11. and your answer is 4.1 X 10^-8. are mine wrong or I missed a step?
Ain Farhana Yes it is. Keq is just a general expression, while Kc, Kp, Kw, etc are the Keq expression but refer to a specific circumstance. Keq is kind of like saying car, but then specifying the type of car by using Kc, Kp, etc. Kc is the most common form, and refers to using concentrations to determine the equilibrium constant.
Ain Farhana It all depends on the ratio between initial reactants and the Keq. use the "rule of 100" or "5% rule" to determine if you can drop the change for your calculations.
very well made and articulated, thanks!
Diller Thank you for the kind comment!
Best explanation I found of the rule of 100 on RUclips. Thanks
Absolute legend
I appreciate it!
Thank you! It is a very good video!!

is Kc and Keq the same thing??

+Moleqlar ok tq. so we can assume the small x approximation is only when Keq is very small right ?

+Moleqlar ohh ok tq for the help
THANK U SO MUCH
thanks for the help, mate. we stan our chemistry king
Much appreciated! I'm glad I could help😀
