Explanation:
In the chain initiation step, the decomposition of benzoyl peroxide gives benzoyl free radical which further gives phenyl free radical.
Phenyl free radical adds to C=C double bond of ethene and generates a new free radical.
In chain propagating step, the newly generated free radical adds to another ethene molecule to form larger free radical. This process repeats several times.
