A) \[{{K}_{c}}\]
B) \[\sqrt{{{K}_{c}}}\]
C) \[K_{c}^{2}\]
D) \[1/{{K}_{c}}\]
Correct Answer: D
Solution :
\[N{{H}_{3}}\]⇌ \[\frac{1}{2}{{N}_{2}}+\frac{3}{2}{{H}_{2}}\] \[{{K}_{c}}=\frac{{{[{{N}_{2}}]}^{{1}/{2}\;}}{{[{{H}_{2}}]}^{{3}/{2}\;}}}{N{{H}_{3}}}\] and \[\frac{1}{2}{{N}_{2}}+\frac{3}{2}{{H}_{2}}\]⇌\[N{{H}_{3}}\] \[{{K}_{c}}=\frac{[N{{H}_{3}}]}{{{[{{N}_{2}}]}^{{1}/{2}\;}}{{[{{H}_{2}}]}^{{3}/{2}\;}}}\] So for dissociation\[=\frac{1}{{{K}_{c}}}\]
