Spontaneous combustion. 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.
A reaction is said to be spontaneous if it occurs without being driven by some outside force. There are two driving forces for all chemical reactions. The first is enthalpy, and the second is entropy.Entropy (D S) is a measure of the disorder of a system, and systems tend to favor a more disordered system: nature tends toward chaos. Spontaneous reactions occur without outside intervention.here are two driving forces for all chemical reactions. The first is enthalpy, and the second is entropy.
