When 2.0 mol of SO2 and 1.0 mol of O2 were allowed to achieve equilibrium in a container of 1 dm3 at 450 °C, the equilibrium mixture was found to contain 1.25 mol of SO3. A balanced chemical reaction is given below: 2SO2(g) + O2(g) ⇌ 2SO3(g) i. Calculate the value of Kp. ii. Calculate the number of moles of oxygen that has to be added to the equilibrium mixture if the amount of SO3 is increased to 1.75 mol?
