The equilibrium constant for the reaction shown below is Kc=0.0091. If the equilibrium concentrations of A and B are 0.031 M and 0.0823 M, respectively, what is the equilibrium concentration of C?

Explanation:

Hello there!

In this case, according to the given chemical reaction at equilibrium:

It is possible for us to set up the equilibrium expression as shown below:

Whereas Kc, [A] and [B] are known as 0.0091, 0.031M and 0.0823M and it is required to calculate [C]; thus, we solve for it as follows:

Best regards!

they both have a y in them

answer; i believe the correct answer is (solid gold);
