Question

If the enthalpy of vaporization for water is 100 is 186.5 jk^-1mol+-1.The entropy of evaporation

Answer 1

Solution : Given,

The boiling point of water =

Vaporization means the phase changes from liquid to vapor at boiling point.

Formula used :

where,

= entropy of vaporization

= enthalpy of vaporization

= boiling point temperature

Now put all the given values in this formula, we get

Therefore, the entropy of vaporization is

.
