The enthalpy of vaporisation of a liquid...

The enthalpy of vaporisation of a liquid is `30 kJ mol^(-1)` and entropy of vaporisation is `75 J mol^(-1) K^(-1)`. The boiling point of the liquid at `1atm` is :

A

250 K

B

400 K

C

450 K

D

600 K

Text Solution

Verified by Experts

The correct Answer is:
B
`dS=(dQ_(rev))/(T), T= (30xx10^(3))/(75), T=400 K`.
