Answer 1

according to Le - Chatelier's principle,
it states that a change in any of the factors that determine the equilibrium conditions of a system will cause the system to change in such a manner so as to reduce or to counteract the effect of the change .

after applying the rules , we get
(a) addition of H2 ( increasing concentration of reactants ) means equilibrium shifts forward direction ( hence, more products is formed )

(b) addition of CH3OH : 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 CH3OH : equilibrium shifts in forward direction.

Answer 2

Answers

1) the reaction will shift in forward direction.

2) the reaction will shift in backward direction.

3) the reaction will shift in backward direction.

4) the reaction will shift in forward direction.

hope it helps!!!
