Chemical Thermodynamics Question 13
Question: If the enthalpy of vaporization for water is 186.5 kJ $ mo{{l}^{-1}} $ , the entropy of its vaporization will be [CPMT 1988; DCE 2000]
Options:
A) $ 0.5,J{{K}^{-1}}mo{{l}^{-1}} $
B) $ 1.0,J{{K}^{-1}}mo{{l}^{-1}} $
C) $ 1.5,J{{K}^{-1}}mo{{l}^{-1}} $
D) $ 2.0,J{{K}^{-1}}mo{{l}^{-1}} $
Show Answer
Answer:
Correct Answer: A
Solution:
$ \Delta S_{vap}=186.5/373=0.5J{{K}^{-1}},mo{{l}^{-1}} $ .
