Chemical Thermodynamics Question 148
Question: $ \Delta G^{o} $ for the reaction $ X+Y $ ⇌ Z is - 4.606 kcal . The value of equilibrium constant of the reaction at $ 227^{o}C $ is $ (R=2.0,cal.,mo{{l}^{-1}}{{K}^{-1}}) $ [Roorkee 1999]
Options:
A) 100
B) 10
C) 2
D) 0.01
Show Answer
Answer:
Correct Answer: A
Solution:
$ \Delta G^{o}=-,2.303,RT,\log K $
$ -,4.606=-,2.303\times 0.002\times 500,\log K $
$ \log ,K=2,K=100 $ .
