Hi i am having trouble with this portion of the question. Please provide handwritten solution for better understanding CO(g) + Cl2(g) COCl2(g) The above reaction obeys the mechanism: Cl2 --> 2Cl Fast equilibrium Cl + CO--> COCl Fast equilibrium COCl + Cl2 --> COCl2 + Cl Slow 2Cl--> Cl2 Fast 1b) Suppose that: k1/k-1 = 1×10-2 mol L-1, k2/k-2 = 1×106 L mol-1, k3 = 1×10-4 L mol-1 s-1, and k4 = 1×103 L mol-1 s-1.

Part A MISSED THIS? Read Section 15.5 (Pages 650 - 656), 15.7 (Pages 661 - 666) .Suppose that a catalyst lowers the activation barrier of a reaction from 123 kJ/mol to 55 kJ/mol. By what factor would you expect the reaction rate to increase at 25.00 ° C? (Assume that the frequency factors for the catalyzed and uncatalyzed reactions are identical.) Express your answer to two significant figures. > View Available Hint(s) ? |X| X•10n k2 1.03 • 1013 k1 Submit Previous Answers X Incorrect; Try Again; One attempt remaining Since the reaction rate is directly proportional to the rate constant, apply the Arrhenius equation to the two different activation energies. Then divide the rate constant for the catalyzed reaction by the rate constant for the uncatalyzed reaction to determine the factor by which the rate increased. You may want to review Hint 1. Express the ratio of the rate constants at different activation energies. 國國
