Question:

A process will be spontaneous to all temperatures if: ΔH<0 and ΔS>0

ΔH<0 and ΔS<0

ΔH>0 and ΔS<0

ΔH<0 and ΔS>0

ΔH>0 and ΔS>0

Solution:

Solution:- (C) ΔH<0 and ΔS>0
ΔG= ΔH – TΔS
For reaction to be spontaneous process at all temperature, ΔG<0 and it is possible when ΔH<0 and ΔS>0 because it gives ΔG<0.
