In explosive combustion, the rapid expansion of volume causes explosion and production of energy.

Explanation:

Explosive combustion is the combustion in which a substance burns suddenly and produces heat, light, and sound with the help of an external source of heat or pressure.

Eg:- explosion of crackers on applying heat or pressure.

Rapid combustion is the combustion in which a substance burns rapidly with the help of an external source and produces heat within a very short time.

Eg:- Burning of LPG.
