Question:

Describe the effect of:

a) Addition of $\mathrm{H}_{2}$

b) Addition of $\mathrm{CH}_{3} \mathrm{OH}$

c) Removal of CO

d) Removal of $\mathrm{CH}_{3} \mathrm{OH}$

on the equilibrium of the reaction:

$2 \mathrm{H}_{2}(\mathrm{~g})+\mathrm{CO}(\mathrm{g}) \longleftrightarrow \mathrm{CH}_{3} \mathrm{OH}(\mathrm{g})$

Solution:

(a) According to Le Chatelier’s principle, on addition of $\mathrm{H}_{2}$, the equilibrium of the given reaction will shift in the forward direction.

(b) On addition of $\mathrm{CH}_{3} \mathrm{OH}$, the equilibrium will shift in the backward direction.

(c) On removing $\mathrm{CO}$, the equilibrium will shift in the backward direction.

(d) On removing $\mathrm{CH}_{3} \mathrm{OH}$, the equilibrium will shift in the forward direction.
