  1. Spontaneous change is one in there is:
    1. A lowering of entropy
    2. A lowering of free energy
    3. Increase in free energy
    4. An increase in Internal energy
Correct Option: B

Entropy and enthalpy together make a new quantity, the Free Energy which, under conditions of constant temperature and pressure, determines the direction of spontaneous change. All spontaneous processes have a negative change in free energy.
