The correct thermodynamic conditios for the spontaneous reaction at all temperature is-

A

`DeltaH lt 0 and DeltaS gt0`

B

`DeltaH lt 0 and DeltaS lt0`

C

`DeltaH lt 0 and DeltaS=0`

D

`DeltaG gt0 and DeltaS lt0`

Text Solution

Verified by Experts

The correct Answer is:
A
At constant temperature and pressure, the reaction is to be spontaneous if `DeltaG lt0`. According to the Gibbs free energy `DeltaG=DeltaH-TDeltaS , DeltaG` will be negative at any temperature if `DeltaH lt 0 and DeltaS gt0`.
