The diagram shown here represents the equilibrium state for the reaction A2(g) + 2 B(g) ? 2 AB(g) .
(a) Assuming the volume is 2 L, calculate the equilibrium constant Kc for the reaction.
(b) If the volume of the equilibrium mixture is decreased, will the number of AB molecules increase or decrease?
