For the following reaction, the gases A, B, and C are at equilibrium. If additional amount of gas A is introduced, the equilibrium constant K: A(g) + B(g) C(g) a) Increases because by adding A, more products are made and the product to reactant ratio increases. b) Decrease because A is a reactant so the product to reactant ratio decreases c) Does not change because [B] and [C] do not change. d) Does not change as long as the temperature...

Decide which of the following statements are True and which are False about equilibrium systems: For the following reaction: CaCO3(s) = CaO(s) + CO2(g) the (CaCO3] appears in the denominator of the equilibrium expression. For the following reaction: H2(g) + F2(g) = 2HF(g) the values of K and Kp are not the same. The value of K at constant temperature depends on the amounts of reactants and products that are mixed together initially. A large value of K means the...
