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 are k1, k2, kw and kg?

In a chain reaction, the reaction rate constant for the chain initiation step reaction is given by k1,
the reaction rate constant for the chain propagation step reaction is given by k2,
the reaction rate constant for the chain termination step reaction is given by k3 but as the destruction of radical in the rate termination step may result in two ways, i.e. at the wall of the vessel or by direct collision with another radical, therefore the rate constant for termination step is divided into two parts as in the rate constant for the reaction taking place at the wall is given by kw and the rate constant for the reaction in which direct collision takes place is referred as kg.
