In any spontaneous process, the __________ free energy decreases.

A. Helmholtz

B. Gibbs

C. Both A & B

D. Neither A nor B

Answer: Option C

Solution(By Examveda Team)

For any spontaneous process $$dG \leqslant 0,\,\,dA \leqslant 0$$
And usually spontaneous process takes place when there are finite differences so, the process will be usually irreversible.
Hence $$dG < 0\,\,\& \,\,dH < 0$$
So, free energy goes on decreasing and when the finite difference becomes infinitesimal difference it becomes constant.
