Answer:

Rapid Combustion is a form of combustion , otherwise known as fire, in which large amounts of heat & light energy are released, which often results in a flame. Example :- Burning of matchstick, Combustion of LPG

Spontaneous combustion or spontaneous ignition is a type of combustion which occurs by self-heating (increase in temperature due to exothermic internal reactions), followed by thermal runaway (self heating which rapidly accelerates to high temperatures) and finally, autoignition.
