A reaction occurs with the following stoichiometry:

The concentration of A was measured vs. time after mix ing; the data are the following:

a. There is no dependence of rate on P. What is the order of the reaction? Calculate the rate coefficient and give the units.

---

b. Propose a mechanism that is consistent with the kinet ics and stoichiometry of the reaction. Write differential equations for your mechanism and relate the measured k to the k's in your mechanism.

---

c. The data given above were measured at 0°C. When the reaction was studied at 10°C, the rate coefficient doubled. Calculate the activation energy in kJ mol-1.
