Question

Write equilibrium constant expressions for both forward and reverse reaction for the synthesis of ammonia by the Haber process.

✓

Answer

Synthesis of ammonia by Haber process:
$ N _{2( g )}+3 H _{2( g )} \rightleftharpoons 2 NH _{3( g )} $
Forward reaction: $K _{ C }=\frac{\left[ NH _3\right]^2}{\left[ N _2\right]\left[ H _2\right]^3}$
Reverse reaction: $K _{ C }^{\prime}=\frac{\left[ N _2\right]\left[ H _2\right]^3}{\left[ NH _3\right]^2 \text { }}$
