What are the characteristics of a Chain Reaction?

Chain reaction is defined as a complex sequence of elementary steps. The various steps can be classified as :
1. Chain Initiation Step
2. Chain Propagation Step
3. Chain Inhibition Step
4. Chain Termination Step

What is Non-Stationary Chain Reaction?

In non- stationary chain reaction, the chain propagation step include reaction which consumes one radical and produces more than one radical.
Since reaction rate is expected to be proportional to the concentration of radicals, that the reaction proceeds with such a large rate that an explosion occurs.
The occurrence of an explosion depends on the temperature and pressure of the reacting system.
