A particular reaction at `27^(@)C` for which `Delta H gt 0` and `Delta S gt 0` is found to be non-spontaneous. The reaction may proceed spontaneously if

A

The temperture is decreased

B

The temperature is kept constant

C

The temperature is increased

D

It is carried in open vessel at `27^(@)` C

Text Solution

Verified by Experts

The correct Answer is:
C
`DeltaG = DeltaH - TDeltaS`
If `DeltaG = -ve rArr` reaction is spontaneous `DeltaH gt 0` and `DeltaS gt 0`
It implies that entropy term can be make `DeltaG` negative which is possible of higher temperature.
