Chemical Thermodynamics Question 409
Question: What is the entropy change (in $ J{{K}^{-1}},mo{{l}^{-1}} $ ) when one mole of ice is converted into water at $ 0{}^\circ C $ - (The enthalpy change for the conversion of ice to liquid water is $ 6.0kJmo{{l}^{-1}} $ at $ 0{}^\circ C $ )
Options:
A) 21.98
B) 20.13
C) 2.013
D) 2.198
Show Answer
Answer:
Correct Answer: A
Solution:
- $ \Delta S(per,mole)=\frac{\Delta Hpermole}{T}=\frac{6000}{273} $
$ =21.98,J{{K}^{-1}}~mo{{l}^{-1}} $
