According to the mechanism below, what is the correct expression for the rate of consumption of A? In the mechanism, M is a molecule that collides with A and A* is a highly-energized form of A.

Step 1 (reversible): A + M <---> A* + M rate constants k1 and k-1

Step 2 (irreversible): A* ---> C rate constant k2

(a) Rate = [C] / [A]

(b) Rate=k1+k2-k-1-k-2

(c) Rate=k1k2 / (k-1+k-2)

(d) Rate = k1k2 [A] [M] / k-1

(e) Rate = k1k2 [A] / (k-1+k2[M])

(f) Rate = [A] / [C]

(g) Rate = k1k2 [A]

(h) Rate = k1[A]

(i) Rate = k1 [A] [M] / (k-1[M] + k2)

(j) Rate = (k1 [A] [M] + k-2[C] ) / (k-1[M] + k2)

(k) Rate = k1k2 [A] [M] / (k-1[M] + k2)

(l) Rate = (k1+k2-k-1-k-2) [A]
