Decribe 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)(g)+CO(g) hArr CH_(3)OH(g)`

Explanation

a) According to Le Chatelier’s principle, on addition of `H_(2)`, the equilibrium of the given reaction will shift in the forward direction.
(b) On addition of `CH_(3)OH`, 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.
