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=-ve$	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, $\Delta H-T\Delta S<0$
