The condition for a reaction to occur spontaneously is -

A

`DeltaH` must be negative

B

`DeltaS` must be netagive

C

`(DeltaH-TDeltaS)` must be negative

D

`(DeltaH+TDeltaS)` must be negative.

Text Solution

Verified by Experts

The correct Answer is:
C
At constant temperature and pressure, for a spontaneous process of the reaction `Delta G lt0`. According to Gibbs equation `DeltaG=DeltaH-TDeltaS`. Therefore the condition of spontaneity is, `DeltaH-TDeltaS lt0`.
