Derive an expression for the time dependence of the free radical concentration
Solution:
The expression are as below,
Time dependence of free radical concentration,
Initiation step
Propagation step
The reaction undergoes two different mode of termination are shown below,
The rate of initiator decomposition is,
The rate of termination step is,
by steady-state assumption we get,
The measurable term of radical concentration expression is,
The free radical concentration with respect to time is,
