a) Consider the production of chlorine using the following reaction: 4NH3(g) + 5O2(g) = 4NO(g) + 6H₂O(g) AH = -906 kJ mol-¹ When 0.45 mol of NH3, 0.20 mol of O2 and 0.10 mol of NO were initially mixed in a 5.0 L vessel and the mixture allowed to attain equilibrium, it was found that 0.20 mol of NO was present at equilibrium at 10 minutes. The temperature was kept constant. i. Define equilibrium. ii. Write the equilibrium expression, Kc. iii. Calculate the number of moles of each species present at equilibrium by constructing an ICE table. Show your working. iv. Calculate the value of Kc for this reaction.

Transcribed Image Text:a) Consider the production of chlorine using the following reaction:
4NH3(g) + 502(g) = 4NO(g) + 6H₂O(g)
AH = -906 kJ mol-¹
When 0.45 mol of NH3, 0.20 mol of O₂ and 0.10 mol of NO were initially mixed in a 5.0 L vessel and
the mixture allowed to attain equilibrium, it was found that 0.20 mol of NO was present at equilibrium
at 10 minutes. The temperature was kept constant.
