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...

Which of the following is true? When the value of Q is large, the equilibrium lies on the product side of the equilibrium reaction. When the value of K is large, the equilibrium lies on the reactant side of the equilibrium reaction. A small value of K means that the equilibrium concentrations of the reactants are small compared to the equilibrium concentrations of the products. A large value of K means that the equilibrium concentrations of products are large compared...
