Derive an expression for the rate of disappearance of a species A in a photochemical reaction for which the mechanism is:

Hence, show that rate measurements will give only a combination of k2 and k3 if a steady state is reached, but that both may be obtained if a steady state is not reached.

(1) initiation with light of intensity 1, (2) propagation, (3) termination. AR-+R- A +R+ R.+B R +R R2
