Chemical Thermodynamics Question 334
Question: If a reaction involves only solids and liquids which of the following is true-
Options:
A) $ \Delta H<\Delta E $
B) $ \Delta H=\Delta E $
C) $ \Delta H>\Delta E $
D) $ \Delta H=\Delta E+\Delta nRT $
Show Answer
Answer:
Correct Answer: D
Solution:
$ \Delta H=\Delta E+P\Delta V $ , for solid and liquid, $ \Delta V=0 $ or $ \Delta H=\Delta E+\Delta nRT $ , for solids and liquids $ \Delta n=0 $
