A reaction occurs spontaneously if:

A

`TDeltaS=DeltaH` and both `DeltaH` and `DeltaS` are positive

B

`TDeltaSgtDeltaH` and both `DeltaH` and `DeltaS` are positive

C

`TDeltaSgtDeltaH` and both `DeltaH` and `DeltaS` are positive

D

`TDeltaSgtDeltaH` and both `DeltaH` and `DeltaH` is positive and `DeltaS` is negative

Text Solution

Verified by Experts

The correct Answer is:
A
For spontaneous reaction `DeltaG=-ve`
`DeltaG=DeltaH-TDeltaS`
`DeltaH=+ve,DeltaS=+ve` and `TDeltaSgtDeltaH`
