Chemical Thermodynamics Question 431
Question: At constant T and P, which one of the following statements is correct for the reaction, $ CO(g)+\frac{1}{2}O_2(g)\to CO_2(g) $
Options:
A) $ \Delta H $ is independent of the physical state of the reactants of that compound
B) $ \Delta H,>,\Delta E $
C) $ \Delta H,<,\Delta E $
D) $ \Delta H=\Delta E $
Show Answer
Answer:
Correct Answer: C
Solution:
- $ \Delta n_{g}=1-\frac{3}{2}=\frac{-1}{2} $ , As $ \Delta n_{g} $ is negative, thus $ \Delta H<\Delta E $ .
