Consider the following elementary reaction:

CFCl3

(g)

→CFCl2

(g)

+Cl

(g)

Suppose we let

k1

stand for the rate constant of this reaction, and

k−1

stand for the rate constant of the reverse reaction.

Write an expression that gives the equilibrium concentration of

CFCl3

in terms of

k1

,

k−1

, and the equilibrium concentrations of

CFCl2

and

Cl

.
