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...
