Question

Match the List-II ans List-II and List III:

List-I	List-II	List-III
A. $\Delta G>0$	X. $\Delta S>0$	1. Non-spontaneous
B. $\Delta G<0$	Y. $\Delta S<0$	2. Spontaneous
C. $\Delta G=0$	Z. $\Delta S=0$	3. Equilibrium

select the correct answering from the following codes:

• A. A-(Y, 1) B-(X, Y) C-(Z, 3)
• B. A-(X, 2) B-(Y, 3) C-(Z, 1)
• C. A-(X, 3) B-(Y, 1) C-(Z, 2)
• D. A-(Y, 1) B-(X, 3) C-(Z, 2)

Answer 1

The correct option is A A-(Y, 1) B-(X, Y) C-(Z, 3)

According to the third law, the entropy change of a spontaneous process is always greater than zero.

For spontaneous process $⟹\Delta G<0and\Delta S>0$

For non-spontaneous process $⟹\Delta G>0and\Delta S<0$

For equilibrium process $⟹\Delta G=0and\Delta S=0$
