Question

Describe the effect of 

(a) addition of H2 

(b) addition of CH3OH 

(c) removal of CO 

(d) removal of CH3OH on the equilibrium of the reaction: 

2H_2(g) + CO _(g) ⇌ CH₃OH _(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. 

Answer 2

(a) addition of H2 equilibrium will shift on RHS. 

(b) addition of CH3OH equilibrium will shift on LHS. 

(c) removal of CO equilibrium will shift on LHS. 

(d) removal of CH3OH equilibrium will shift on RHS.
