Spontaneous change is one in which there is:
A
A lowering of entropy
B
A lowering of free energy
C
Increase in free energy
D
An increase in Internal energy
Correct Answer: A lowering of free energy
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.
