Question

The value of K for the reaction, $N_2+3H_2\rightleftharpoons 2N{H}_3$, can be increased by applying high pressure or by using a catalyst.

• A. True
• B. False

Answer 1

The correct option is B False

Given equilibrium reaction

$3H_2+N_2\rightleftharpoons 2N{H}_3$

$K_{eq}=\frac{[N{H}_3{]}^2}{\left[H_2{]}^3\right[N_2]}$

Case -1

If we increases the pressure, the reaction shifted towards forward direction but after same time it attains same equilibrium position according to be chatalior principal.

Case - 2

Addition of any catalyst will favour both forward and backward direction in same ratio therefore $K_{eq}$ remains unaffected by any catalyst.
Thus the given statement is false.
