Question

Describe the effect of:

1. addition of H2
2. addition of CH3OH
3. removal of CO
4. removal of CH3OH

on the equilibrium of the reaction:
$2H_2(g) + CO (g) ⇋ CH_3OH (g)$

Answer 1

(a) According to Le Chatelier's principle, on addition of H2, the equilibrium of the given reaction will shift in the forward direction.

---

(b) On addition of CH3OH, the equilibrium will shift in the backward direction.

---

(c) On removing CO, the equilibrium will shift in the backward direction.

---

(d) On removing CH3OH, the equilibrium will shift in the forward direction.
