The decomposition of limestone may be spontaneous if it also does not require continual input of energy.

The reverse reaction is exothermic and spontaneous.
This is because, all thermal decomposition ( and all decomposition processes ) is an exothermic process. Well, if you need a full explanation, here goes. More energy is given off to form bonds then taken in to break bonds hence it is an exothermic reaction. Also, decomposition gives off heat energy.
Rusting is an oxidation and can be considered as a synthesis of an iron oxide.
The spontaneous decomposition of unstable atomic nuclei.
The decomposition of limestone may be spontaneous if it also does not require continual input of energy.
The decomposition of hydrogen peroxide is spontaneous but some catalysts increase the speed of reaction.
The reaction is spontaneous above 371 K.
Radioactive dating of rock samples determines the age of rocks from the time it was formed. Geologist determine the age of rocks using radioactive dating. The radioactive dating relies on spontaneous decomposition into other element. The spontaneous decomposition is called radioactive decay.

It shows dehydration and decomposition.
Incorrect nowadays.

Spontaneous Thursday is a day when a blogger posts random spontaneous things in his or her blog without writing it earlier and also without caring how it affects the community.
