  For the reaction: \[{{N}_{2}}(g)+3{{H}_{2}}(g)\underset{{}}{\leftrightarrows}2N{{H}_{3}}(g)\] Equilibrium constant \[{{K}_{c}}=\frac{{{[N{{H}_{3}}]}^{2}}}{[{{N}_{2}}]{{[{{H}_{2}}]}^{3}}}\] Some reactions are written below in Column I and their equilibrium constants in terms of \[{{K}_{c}}\] are written in Column II. Match the following reactions with the corresponding equilibrium constant.  

Column l (Reaction)	Column II (Equilibrium constant)
(i) \[2{{N}_{2}}(g)+6{{H}_{2}}(g)\underset{{}}{\leftrightarrows}4N{{H}_{3}}(g)\]	(a) \[2{{K}_{c}}\]
(ii) \[2N{{H}_{3}}(g)\underset{{}}{\leftrightarrows}{{N}_{2}}(g)+3{{H}_{2}}(g)\]	(b) \[K_{c}^{\frac{1}{2}}\]
(iii) \[\frac{1}{2}{{N}_{2}}(g)+\frac{3}{2}{{H}_{2}}(g)\underset{{}}{\leftrightarrows}N{{H}_{3}}(g)\]	(c) \[\frac{1}{{{K}_{c}}}\]
	(d) \[K_{c}^{2}\]

 

Answer:

  (i-d) (ii-c) (iii-b)
