Question

Select the conditions which represent the criteria for spontaneity of a process in a closed system, from the following given conditions:

Serial Number	Conditions
1.	(dG)P,T > 0
2.	(Δ S)universe > 0
3.	(dU)S,V > 0
4.	(dH)S,P < 0
5.	(dS)U,V < 0
6.	(dS)H,P > 0

(Answer by adding the serial numbers of the correct conditions.)

Spontaneous requires (dG) P,T <0, (Δ S) univ >0, (dU) S,V <0, (dH) S,P <0, (dS) U,V >0, (dS) H,P >0. So 2, 4 and 6 are correct; 1, 3, 5 have the wrong sign. Sum = 2+4+6 = 12. Ans = 0012.
