An equilibrium mixture from the following reaction was found to contain 1.20 mol dm-3 of A, 1.00 mol dm-3 of B, and 0.80 mol dm-3 of C. A (g) ⇌ B (g) + C (g) a. What is the value of Kc for this reaction? b. If the volume of the reaction vessel were suddenly doubled while the temperature remained constant, determine whether the system be at equilibrium. If not, what must occur to establish equilibrium? c. If the initial volume of the reaction vessel were halved, while the temperature remains constant, determine whether the system be at equilibrium. If not, what must occur to establish equilibrium?
