Question

Molar Heat Capacities of Vapour and a liquid state of a substance is 38.7 J/ K mol and 63.14 J/ K mol respectively. If Latent heat of Vapourisation is 836.2 KJ/mol at 300 k. Its Value at 400k is​

Answer 1

Answer:

Since boiling occurs at equilibrium conditions so ΔG=0

Now,

T=

ΔS

ΔH

T=

16J/mol/K

6000J/mol

T=375K

Hence, the boiling point of the liquid is 375K.
