Select all of the correct statements about equilibrium from the choices below. At equilibrium the rates of forward and reverse reactions are equal. At equilibrium all reactions stop. At equilibrium the rate of change of product concentration is zero. At equilibrium the speed of a reaction equals its rate constant. As a reaction proceeds forward toward equilibrium the forward rate constant drops. At equilibrium the forward rate constant equals zero.

Select all of the correct statements about equilibrium from the choices below. At equilibrium the rates of forward and reverse reactions are equal. At equilibrium the rate of change of product concentration is zero. At equilibrium the forward rate constant equals zero. As a reaction proceeds backwards toward equilibrium the reverse rate drops. As a reaction proceeds forward toward equilibrium the reactant concentrations drop. At equilibrium no more reactants are transformed into products.

Show that the reaction A - B + C, which is first-order forward (rate constant k) and second-order reverse (rate constant k), relaxes exponentially for small displacements from equilibrium. Find an expression for the relaxation time in terms of k, and k. (Hint: Let x be a small displacement from equilibrium. For such a displacement, xº is negligible.)
