Spontaneous change is one in there is:
-
- A lowering of entropy
- A lowering of free energy
- Increase in free energy
- An increase in Internal energy
- A lowering of entropy
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.
