State the thermodynamic conditions for spontaneous occurrence of a process.

The correct thermodnamic conditions for the spontaneous reaction at all temperature 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.

For a spontaneous process :-

The sole criterion for the spontaneity of a process is

In isolated system, find the condition for spontaneous reaction:

Considering entropy (S) as a thermodynamics parameter, the criterion for the spontaneity of any process is

State the third law of thermodynamics.

State the first law of thermodynamics.

State the first law of thermodynamics.

State the first law of thermodynamics.
