Spontaneous reactions are voluntary reactions which occur with no external intervention. ... Non-spontaneous reactions require an energy input or a catalyst to lower the energy requirements to take place,i.e. they can only occur if energy is put into the reaction from an external source.

Spontaneous and nonspontaneous reactions are the two types of chemical reactions that can occur in the environment. Spontaneous reactions take place on their own under a given set of conditions. However, energy should be provided for the nonspontaneous reactions to proceed. The change in the Gibbs free energy is negative for spontaneous reactions. Therefore, these reactions release energy to the surroundings in the form of heat. In nonspontaneous reactions, the change in the Gibbs free energy is positive. They absorb energy from the environment. On that account, spontaneous reactions are exergonic while nonspontaneous reactions are endergonic. The main difference between spontaneous and nonspontaneous reactions is that spontaneous reactions release free energy from the system, making it more stable whereas nonspontaneous reactions increase the total energy of the system.
