Chlorofluorocarbons (cfcs) are no longer used as refrigerants because they destroy the ozone layer. trichlorofluoromethane (ccl3f) boils at 296.95 k, and its molar heat of vaporization is 24.8 kj/mol.

Explanation:

It is known that entropy is the measure of degree of randomness present in a substance due to the movement of its molecules.

More randomly the atoms are moving from one place to another more will be the entropy of system.

In order to calculate the entropy, we divide the amount of heat transferred by the temperature at which heat transfer occurs.

As the given temperature is 296.95 K and heat of vaporization is 24.8 kJ/mol. Therefore, calculate the molar entropy of vaporization as follows.

Molar entropy of vaporization =

                                                  = 0.08351 kJ/mol K

Thus, we can conclude that molar entropy of vaporization of is 0.08351 kJ/mol K.
