In the equation below, PCl3(g) + Cl2(g) « PCl5(g) the forward reaction is first order in both PCl3 and Cl2 and the reverse reaction is first order in PCl5. (a) Suppose that 2 moles of PCl3 and 1 mole of Cl2 are mixed in a closed 1.0 L container at constant temperature. Draw a graph that shows how the concentrations of PCl3, Cl2, and PCl5 change with time until after equilibrium has been firmly established. Indicate the numerical values on the concentration axis. (b) Give the initial rate law for the forward reaction. (c) Provide a molecular explanation for the dependence of the rate of the forward reaction on the concentrations of the reactants. (d) Provide a molecular explanation for the dependence of the rate of the forward reaction on temperature. Remember to include the Maxwell-Boltzmann graph in your answer.
