Spontaneous reaction is a reaction that occurs without the addition of energy

There are two types of reactions in thermodynamics:

Endothermic reactions -

They are chemical reactions in which the reactants absorb heat energy from the surroundings to form products.
Endothermic reactions are typically non- spontaneous reactions
They generally involve the formation of chemical bonds through the absorption of heat from the surroundings.

Exothermic reactions -

An Exothermic reaction is a chemical reaction that involves release of energy in the form of heat or light.
Exothermic reactions are spontaneous at room temperature
They involve the release of heat energy generated from bond-breakage

Thus we can conclude that spontaneous reaction is a reaction that occurs without the addition of energy
