Question

Match the thermodynamic processes given under Column I with the expressions given under Column II.

	Column I		Column II
A	Freezing of water at 273 K and 1 atm	P	q = 0
B	Expansion of 1 mol of an ideal gas into a	Q	w = 0
C	Mixing of equal volume of two ideal gases at	R	∆Ssys <0
D	Reversible heating of H2(g) at 1 atm from	S	∆U=0
		T	∆G=0

Answer 1

(A-R, T) (B-P, Q, S) (C-P, Q, S) (D-P, Q, S, T)

∆G <0

(C) Mixing of equal volume of ideal gases at constant pressure & temp in an isolated container
