2a. [1 mark] The Contact process involves an exothermic reversible reaction. 2502(g) + O2(g) = 2803(g) K 1 at 200 C and 1 atm Deduce the extent of the reaction at 200 C and 1 atm. 2b. [4 marks) The Contact process operates at a temperature of 450 C and a pressure of 2 atm as optimum conditions for the production of SO3 Outline the reasons for choosing these conditions. Temperature: Pressure: 2c.[2 marks] An engineer at a Contact process plant hypothesized that using pure oxygen, instead of air, would increase the profits. Comment on whether or not her hypothesis is valid, giving your reasons. 2a.
