Question

Match Column-I with Column-II.

Column I		Column II
A	$\Delta H=- ve ; \Delta S=- ve $ $\Delta G =- ve$	p	Reaction will be non-spontaneous at high temperature
B	$\Delta H=-\text { ve ; } \Delta S=-\text { ve }$$\Delta G=+\text { ve }$	q	Reaction will be non-spontaneous at low temperature
C	$\Delta H=+ ve ; \Delta S=+ ve$$\Delta G=+ ve$	r	Reaction will be spontaneous at low temperature
D	$\Delta H =+ ve ; \Delta S=+ ve$$\Delta G=-v e$	s	Reaction will be spontaneous at high temperature

• A. A−(q),B−(r),C−(p),D−(s)
• B. A−(r),B−(p),C−(q),D−(s)
• C. A− (r), B− (q) , C -(s), D -(p)
• D. A−(q),B−(s),C−(p),D− (r)

Answer 1

Answer: (B)

$A -( r ), B -( p ), C -( q ), D -( s )$
For spontaneity, $\Delta H - T \Delta S <0$
