Question

Match List-I with List-II.

List-I (Melting of ice)	List-II (Condition)
A) Ice at $-{10}^{o}C$	1) $\Delta G=0$
B) Ice at $+{10}^{o}C$	2) $\Delta G=+ve$
C) Ice at $0^{o}C$	3) $\Delta G=-ve$

• A. A-1,B-2,C-3
• B. A-3,B-2,C-1
• C. A-2,B-3,C-1
• D. A-1,B-3,C-2

Answer 1

The correct option is C A-2,B-3,C-1

Solution:- (C) $A-2,B-3,C-1$

A we know that the melting of ice below $273K$ is a non-spontaneous process and above $273K$, it is a spontaneous process while at $273K$, the process is in equilibrium.

Hence the value of $\Delta G$ for melting of ice at $-10℃,+10℃$ and at $0℃$ is $>0,<0$ and $=0$ respectively.

Hence the correct answer is-

$A-2,B-3,C-1$.
