Match the column:

	Columm-I		Columm-II
(a)	(ΔGsystem)T,P = 0	(p)	Process is in equilibrium
(b)	ΔSsystem + ΔSsurrounding > 0	(q)	Process is nonspontaneous
(c)	ΔSsystem + ΔS surrounding < 0	(r)	Process is spontaneous
(d)	(ΔGsystem)T,P > 0	(s)	System is unable to do useful work

The correct answer is:

CHECK THE SOLUTION.

→ (p, s); → (r) ; → (q, s) ; → (q, s).

Δ G sys = 0 equilibrium and free energy is zero. So, no useful work.

Δ S universe > 0 Spontaneous process and able to do useful work.

Δ S universe < 0 Nonspontaneous process and unable to do useful work.

Δ G sys > 0 Nonspontaneous process and unable to do useful work
