Describe the effect of: a) addition of H2 b) addition of CH3OH c) removal of CO d) removal of CH3_3OH on the equilibrium of the reaction:

2H2(g)+CO(g)⇌CH3OH(g)2H_2(g) + CO (g) \rightleftharpoons CH_3OH (g)
(a)
Answer

Addition of H2H_2 shifts the equilibrium in the forward (right) direction.

(b)
Answer

Addition of CH3OHCH_3OH shifts the equilibrium in the backward (left) direction.

(c)
Answer

Removal of COCO shifts the equilibrium in the backward (left) direction.

(d)
Answer

Removal of CH3OHCH_3OH shifts the equilibrium in the forward (right) direction.

Explanation

According to Le Chatelier's principle, if a dynamic equilibrium is disturbed by changing the conditions, the position of equilibrium shifts to counteract the change. Adding a reactant or removing a product shifts the equilibrium to the right (forward direction), while adding a product or removing a reactant shifts it to the left (backward direction).
