(a)
Interpretation:
The entropy of vaporization of chloroform has to be estimated.
Concept Information:
Entropy of vaporization: The entropy of vaporization at the boiling temperature of a liquid is related to its enthalpy of vaporization at that temperature.
ΔvapS = ΔvapH (Tb)Tb
Where,
ΔvapS is change in entropy of vaporization,
ΔvapH is change in enthalpy of vaporization,
Tb is the boiling temperature.
(b)
Interpretation:
The entropy change in the surroundings has to be calculated.
Concept Information:
Trouton’s rule: In the vaporization of liquid, the condensed (or less disordered) phase of liquid vaporizes into the gaseous phase, where the dispersed gas occupies approximately same volume whatever its identity.
Then, considering value of the change in entropy of such liquids is constant as 85 JK-1mol-1
Trouton’s rule exception: For exceptional liquids having special kind of interactions like hydrogen bonding and metallic bonding result in the liquid being less disordered than a random jumble of molecules. There exists high value of entropy change.
Entropy of vaporization: The entropy of vaporization at the boiling temperature of a liquid is related to its enthalpy of vaporization at that temperature.
ΔvapS = ΔvapH (Tb)Tb
Where,
ΔvapS is change in entropy of vaporization,
ΔvapH is change in enthalpy of vaporization,
Tb is the boiling temperature.
