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.

Statement: The thermodynamics functions which determines the spontaneity of a process is the free energy. For a process to be spontaneous, the change in free energy must be negative. Explanation:The change in free energy is related to the change in enthalpy and change in entropy. the change in entropy for a process must be always positive if it is spontaneous.

For a process to be spontaneous, DeltaG must be………… .

For a process to be spontaneous, DeltaG must be………… .

For a process to be spontaneous, DeltaG must be………… .

(A): For a process to be spontaneous, the change in free energy must be negative. (R): The change in entropy for a process must always be positive if it is spontaneous.

When spontaneous process occurs then free energy of a system

Explain spontaneity of a process in terms of Gibbs energy.

What is the free energy criterion for a process to occur spontaneously?

A process must be spontaneous (feasible) if:
