Statement: The thermodynamics functions ...

Statement: The thermodynamics functions which determines the spontaneity of a process is the free energy. For a process to be spontaneous, the change in free energy must be negative.
Explanation:The change in free energy is related to the change in enthalpy and change in entropy. the change in entropy for a process must be always positive if it is spontaneous.

A

`S` is correct but `E` is wrong.

B
