The a reaction to be spontaneous at all temperature

A

`DeltaG` and `DeltaH` should be negative

B

`DeltaG` for the reaction is zero

C

`DeltaG` and `DeltaH` should be positive

D

`DeltaH lt DeltaG`

Text Solution

Verified by Experts

The correct Answer is:
A
`DeltaG=DeltaH-TDeltaS`
For spontaneous reaction at all temperature
`DeltaH=-ve`
`DeltaS=+ve`
So `DeltaG=-ve`
`DeltaG=DeltaH-TDeltaS`
For spontaneous reaction at all temperature
`DeltaH=-ve`
`DeltaS=+ve`
So `DeltaG=-ve`
