Gibbs Free Energy & Spontaneity

Assertion :Th...

Question

Assertion :The thermodynamic factor which determines the spontaneity of a process is the free energy. For a process to be spontaneous the free energy must be -ve Reason: The change in free energy is related to the change in enthalpy and change in entropy. The change in entropy for a process must always be positive if it is spontaneous.

Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
