The kinetics of three-stage, successive, first-order reactions.

By Roy Ernest Ballard

2 November 2014

This post is concerned with the kinetics of successive, irreversible, first order reactions. An earlier post on this subject  discussed the kinetics of a two-stage sequence. Here the complete solution is reported for the three-stage sequence:
The solution is:
