Chemical Thermodynamics Question 118
Question: For the reaction, $ C_3H_8(g)+5O_2(g)\to 3CO_2(g)+4H_2O(l) $ at constant temperature, $ \Delta H-\Delta E $ is [CBSE PMT 2003]
Options:
A) - RT
B) + RT
C) - 3RT
D) + 3RT
Show Answer
Answer:
Correct Answer: C
Solution:
$ \Delta H-\Delta E=\Delta nRT $ ; $ \Delta n=-3 $ so, $ \Delta H-\Delta E=-3RT $ .
