Question

Consider the interconversion of A molecules (shaded spheres) and B molecules (unshaded spheres) according to the reaction A ⇌ B.Each of the following series of pictures represents a separate experiment in which time increases from left to right.

-What is the value of the equilibrium constant K_c for the reaction A ⇌ B?

Quizplus · Accepted Answer

The equilibrium constant (K_c) can be calculated by taking the ratio of the concentration of products (B) to the concentration of reactants (A) at equilibrium. In the third experiment, at equilibrium, there are 3 B molecules and 1 A molecule, so the equilibrium constant is 3/1 = 3.
