Which of the following statements is/are CORRECT?   1. For a chemical system, if the reaction quotient (Q) is greater than K, reactant must be converted to products to reach equilibrium.   2. For a chemical system at equilibrium, the forward and reverse rates of reaction are equal.   3. For a chemical system at equilibrium, the concentrations of products divided by the concentrations of reactants equals one.

The Arrhenius equation, expresses the dependence of the rate constant on the reaction temperature. The slope of a plot of ln(k) versus 1/T is equal to
