A) \[\simeq 8\times {{10}^{4}}J\text{ }mo{{l}^{-1}}\]
B) \[\simeq 3.5\times {{10}^{4}}Jmo{{l}^{-1}}\]
C) \[\simeq 2\times {{10}^{4}}Jmo{{l}^{-1}}\]
D) None of these
Correct Answer: A
Solution :
[a] \[\Delta {{G}^{{}^\circ }}=-RT\] ln K \[=-8.314J{{K}^{-1}}\,mo{{l}^{-1}}\times 298K\times 2.303log\text{ }{{10}^{-14}}\] \[=7.98\times {{10}^{4}}\simeq 8\times {{10}^{4}}J\,mo{{l}^{-1}}\]
