Vedclass · Answer

(A) The target reaction is: $2NH_3 + \frac{5}{2}O_2 ightleftharpoons 2NO + 3H_2O$.This can be obtained by manipulating the given reactions:Reverse reaction $(1)$: $2NH_3 ightleftharpoons N_2 + 3H_2$,$K' = \frac{1}{K_1}$Reaction $(2)$: $N_2 + O_2 ightleftharpoons 2NO$,$K_2$Multiply reaction $(3)$ by $3$: $3H_2 + \frac{3}{2}O_2 ightleftharpoons 3H_2O$,$K'' = K_3^3$Adding these three reactions:$(2NH_3 ightleftharpoons N_2 + 3H_2) + (N_2 + O_2 ightleftharpoons 2NO) + (3H_2 + \frac{3}{2}O_2 ightleftharpoons 3H_2O)$Resulting in: $2NH_3 + \frac{5}{2}O_2 ightleftharpoons 2NO + 3H_2O$The equilibrium constant $K$ is: $K = K' 	imes K_2 	imes K'' = \frac{1}{K_1} 	imes K_2 	imes K_3^3 = \frac{K_2 K_3^3}{K_1}$.
