For a process to be spontaneous

For a process to be spontaneous :

Name the two criteria which must be met for a process to be spontaneous regardless of the temperature.

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………… .

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.

A: A non- spontaneous process becomes spontaneous when coupled with a suitable spontaneous reaction. R: The overall free energy of coupled spontaneous reaction is negative.
