Consider the reaction A* -> C

Where A* is the exciting form of A formed through collisions with species B as shown below.

(i) A + B <-> A* + B

Reaction rates for (i) are k1f <--- Forward, and k1b <--- Backwards

a. Calculate dCA*/dt

b. Use PSSA for A* to approximate reaction rate for C (dCC/dt = ???).

(ii) A* -> C

Reaction rate for (ii) is k2
