(a) Consider the reaction below: 2C₂H, (g) + 30(g) DH = -80 kJ Predict the direction of the equilibrium if: (i) the pressure of the system is increased. (ii) O, is added to the system. (iii) the temperature of the system is decreased. (iv) C,H, is reduced from the system. (4 marks) concentration of HF is 4CO (g) + 2H₂O(g) (b) Given the reaction below. 2HF (g) H₂(g) + F₂ (g) 0.10 M of HF was filled in a 1.0 L flask and was allowed to reach 0.03 M. Calculate Kc. (6 marks) equilibrium. At equilibrium, it was found that the (CLO2:PLO 1:C4) pressure of the flask is (c) A mixture of gases has been added in 1.0 L flask at 30 °C. It contains 2.85 moles 280 kPa. Calculate : NH₂, 1.05 moles N, and 0.75 moles H₂. The total 2NH, (g) (i) partial pressure for each gas. (3 marks) (ii) Kp value (2 marks) (iii) Kc value for the reaction.
