Answer: The correct answer is Option A.

Step-by-step explanation:

Gibbs' free energy is defined as the energy which is used to do work. It is represented as
\Delta G

It is also defined as the enthalpy change of the system minus the product of temperature and entropy change.

Mathematically,


\Delta G=\Delta H-T\Delta S

where,


\Delta G = Gibbs' free energy


\Delta H = Enthalpy change


\Delta S = Entropy change

T = absolute temperature

When
\Delta G comes out to be negative, the reaction is spontaneous and if comes out to be positive, the reaction is non-spontaneous.

Hence, the correct answer is Option A.
