In which case, a spontaneous reaction is possible at any temperature

A

`DeltaH lt 0, DeltaS gt 0`

B

`DeltaH lt 0, DeltaS lt 0`

C

`DeltaH gt 0, DeltaS gt 0`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
C
`DeltaG=DeltaH-TDeltaS`
For spontaneous reaction at any temperature `DeltaG` must be negative. It is obtained when `DeltaH=-ve`
`DeltaS=+ve`
