Interpretation:
The entropy changes
Concept Introduction:
In
The equation given below helps us to calculate the change in free energy in a system.
At a temperature of normal boiling point, the gaseous state of the system will be in equilibrium with the liquid state. The free energy change in the system will be zero. Taking the free energy value as zero, molar entropy of sublimation can be calculated using the following equation.
