Time Dependence of Chain Propagation

Having written the kinetic equations for concentration n of active centers A and for reaction product C 

1 Actually, 3 may exceed unity if the active radical produces more than two free valences as in the case H -h O2 - HOg + 0. In this case, 3 cannot be treated literally as a probability. However, all the expressions below remain correct for i 1. 

When no more active centers are produced, the reaction attenuates exponentially
