find the amount of C

Question

for the given reaction equilibrium constant is 9. If A and B are taken in equal amounts then amount of C at equilibrium will be?

the chemical reaction is A+B↔C+D

Answer 1

First you need to know the equilibrium expression. The equilibrium expression for this reaction is

 

K = [C][D]/[A][B]  where all the concentrations are at equilibrium.

 

Since A and B have equal amounts then the above expression simplifies an all you have to do is to solve for the unknown [C].
