For the generic single-step reaction, below, draw an Arrhenius plot (In(k) vs 1/T). Is the reaction faster at high temperatures or low temperatures? A + B rightarrow^k AB Now consider the reaction B + C + D rightarrow E which is comprised of the two steps shown below where all reactions are first order for all species. The first step is a rapid equilibrium between B, C, and BC, with equilibrium constant K=[BC]/([B][C]). B + C BC BC + D rightarrow E Show that the dependence of the overall reaction rate on temperature is given by the equation below, where Delta H degree is the enthalpy change for the first step and E_a is the activation barrier for the second step k = A exp[-(E_a + Delta H^-degree)/RT]
