How does `T DeltaS` determine the spontaneity of process?

Text Solution

Verified by Experts

Processes in which `DeltaH = +ve` and `DeltaS = +ve. DeltaG` will be -ve if `T DeltaS gt DeltaH`, then reaction will be spontaneous. When `DeltaH = - ve` and `DeltaS =- ve, DeltaG` will be `-ve` if `T DeltaS lt DeltaH`.

Spontaneity of a process

For spontaneous process:

Criteria for spontaneity of process is :-

Assertion (A): The thermodynamic factor which determines the spontaneity of a process is the free energy. For a process to be spontaneous the free energy must be-ve. Reason (R ) : The change in free energy is related to the change in a process must always be positive if its is spontaneous.

The sole criterion for the spontaneity of a process is

For a spontaneous process,
