The favourable conditions for a spontaneous reaction are

A

`TDeltaS gt DeltaH`, `DeltaH=+ve`, `DeltaS=+ve`

B

`TDeltaS gt DeltaH`, `DeltaH=+ve`, `DeltaS=-ve`

C

`TDeltaS = DeltaH`, `DeltaH=-ve`, `DeltaS=-ve`

D

`TDeltaS = DeltaH`, `DeltaH=+ve`, `DeltaS=+ve`

Text Solution

Verified by Experts

The correct Answer is:
A

`DeltaG=DeltaH-TDeltaS`. For a process to be spontaneous, `DeltaG` should be `-ve`. In `(A) DeltaH` is `+ve` and `DeltaS` is `+ve` and `TDeltaS gt DeltaH`
`0 gt DeltaH-TDeltaS`
`0 gt DeltaG`
i.e., process is spontaneous
