Question: The enthalpy of vapourization of a liquid is $ 30,kJ,mo{{l}^{-1}} $ and entropy of vapourization is $ 75,J,mo{{l}^{-1}}K $ . The boiling point of the liquid at 1 atm is [IIT JEE (Screening) 2004]
Options:
A) 250K
B) 400K
C) 450K
D) 600K
Show Answer
Answer:
Correct Answer: B
Solution:
$ dS=\frac{d{Q_{rev.}}}{T} $ ; $ T=\frac{30\times 10^{3}}{75} $ ; $ T=400K $
