Consider the following equilibrium, aligned & 2 No (g) N ₂+ O ₂ ; K_ G ₁ =2.4 10²⁰ & No (g)+ 1 2 Br ₂( ~g ) NoBr (g) ; K_ C₂ =1.4 aligned Calculate K_C for the reaction, 1 2 ~N ₂(g)+ 1 2 O ₂(g)+ 1 2 Br ₂(g) NOBr (g)

Step-by-step solution

For, 2 NO ( g ) N ₂+ O ₂ K _ C ₁ = [ N ₂ ] [ O ₂ ] [ NO ]^2 =2.4 10²⁰ For, aligned & For, NO (g)+ 1 2 Br ₂(g) NOBr (g) & K_ C₂ = [ NOBr ] [ NO ] [ Br ₂ ]^ 1 / 2 =1.4 & and K_C= [ NOBr ] [ N ₂ ]^ 1 / 2 [ O ₂ ]^ 1 / 2 [ Br ₂ ]^ 1 / 2 & or K_C= 1 K_ C ₁ K_ C₂ = 1 2.4 10²⁰ 1.4 & K_C=8.96 10⁻¹¹ aligned
