Chemical Thermodynamics Question 96
Question: For the reaction $ N_2+3H_2 $ ⇌ $ 2NH_3;,\Delta H= $ [Roorkee 2000; CBSE PMT 1991, 2002]
Options:
A) $ \Delta E-RT $
B) $ \Delta E-2RT $
C) $ \Delta E+RT $
D) $ \Delta E+2RT $
Show Answer
Answer:
Correct Answer: B
Solution:
$ \Delta H=\Delta E+\Delta nRT $ Since $ \Delta n=-2 $ Than $ \Delta H=\Delta E-2RT $ .
