Question

Describe the effect of :
a) addition of $H_2$
b) addition of ${CH}_{3}OH$
c) removal of $CO$
d) removal of ${CH}_{3}OH$ on the equilibrium of the reaction :
$2H_2\left(g\right)+CO\left(g\right)\rightleftharpoons {CH}_{3}OH\left(g\right)$

Answer 1

(a) addition of $H_2$

( increasing concentration of reactants )

means equilibrium shifts forward direction

(b) addition of $C{H}_{3}OH$

(increases in concentration of products )

means equilibrium shifts the backward direction.

(c) Removal of $CO$

if we remove the $CO$ then

equilibrium shifts the backward direction.

(d) Removal of $C{H}_{3}OH$

equilibrium shifts in forward direction.
