1. (i) H₂ will decrease

(ii) H₂ will increase

2. (i) Shift right

(ii) Shift left

(iii) Shift left

(iv) Shift left

3. (i) Shift left

(ii) Shift right

(iii) Shift left

4. (i) H₂O will increase

(ii) H₂O will increase

Explanation:

1. For the reaction, N₂ (g) + 3H₂ (g) ↔ 2NH₃ (g) + 22 kJ

(i) When the NH₃ is removed, the concentration of the products is reduced favoring the consumption of further reactants hence the H₂ will decrease

(ii) When N₂ is removed, N₂ will become the limiting reactant resulting in the presence of excess H₂, hence H₂ will increase

2. 2NO (g) + H₂ (g) ↔ N₂O (g) + H₂O (g) 36 kJ

(i) When NO is added, it will favor the increase of the reaction and the equilibrium will shift to the right

(ii) H₂ is removed, it will favor the decomposition of the products hence the equilibrium will shift to the left

(iii) When N₂O is added, it will cause the increase in the partial pressure of the products which will result in the increase in the partial pressures of the reactants to compensate, hence the equilibrium will shift to the left

(iv) When H₂ is removed it will cause the equilibrium to shift left as more products will decompose to form the balance H₂

3. For the reaction;

CO₂ (g) + H₂ (g) + heat ↔ CO (g) + H₂O (g)

(i) When CO is added, there will be an excess partial pressure of the products and the equilibrium will shift left

(ii) When CO₂ is added, there will be an excess partial pressure of the reactants which will favor the formation of the products and the equilibrium will shift right

(iii) When H₂ is removed, there will be an decrease in the partial pressure and concentration of the reactants which will favor the decomposition of the products to balance up the partial pressures of the reactant and the equilibrium will shift left

4. In the reaction  2NO (g) + H₂ (g) ↔ N₂O (g) + H₂O (g) + heat

(i) When NO is added, the concentration of the reactants will increase, hence increasing the likelihood of the formation of more products and the equilibrium will shift to the right and H₂O will increase

(ii) When N₂O is removed, the partial pressure and concentration of the products will reduce hence to balance up the partial pressures of the reacting mixture, more products will be formed and H₂O will increase.
