Write the expression for the equillibrium constant $(K_{c})$ for the following reactions.
(i) $H_{2} (g) + I_{2} (g) ⇋ 2 H I (g)$
(ii) $4 {N H}_{3} (g) + 5 O_{2} (g) ⇋ 4 N O (g) + 6 H_{2} O (g)$

Solution

$(I) H_{2 (g)} + I_{2 (g)} ⇌ {2 H I}_{(g)}$
$K_{C} = \frac{{[H I]}^{2}}{[H_{2}] [I_{2}]}$
$(I I) 4 {N H}_{3 (g)} + {S O}_{2 (g)} ⇌ 4 {N O}_{(g)} + 6 H_{2} O_{(g)}$
$K_{C} = \frac{{[N O]}^{4} {[H_{2} O]}^{6}}{{[{N H}_{3}]}^{4} {[O_{2}]}^{5}}$
