Answer:
10. methanol would be more.
11. methanol would be more.
12. methanol would remain the same.
13. CO would be less.
Step-by-step explanation:
10. Methanol increases because the forward reaction is favoured with increase in temperature and thus it is endothermic.
11. Methanol increases because the forward reaction is favoured with decrease in volume thus increasing pressure decreases the volume of the vessel.
12.Methanol remains the same because the hydrogen added is its raw material but the CO is acting as a limiting reactant for the formation of methanol.
13. Carbon monoxide becomes less because it will rapidly combine with hydrogen added to form methanol and then later be a limiting reactant when hydrogen is still present
