When a chemical reaction is at equilibrium, the forward and reverse reactions occur at the same rate. The concentrations of the different compounds in the reactions will remain constant. The relationship between the concentrations of the reactants and products is expressed as the equilibrium constant, K.. Part A Balance this equation, and then enter the coefficients, in order, below. CCl,(g) + O2(g) = COCl (g) - Cl (8) Express your answer as integers separated by commas (e.g. 1, 2, 3,...

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.)
