Spontaneous Process:

A spontaneous process occurs naturally without the need for external intervention. It tends to lead to an increase in the overall entropy of the universe.

Gibbs Free Energy:

Gibbs free energy (ΔG) combines both enthalpy (∆H) and entropy (∆S) changes to determine whether a process is spontaneous or non-spontaneous.
