Pure sulphur is burnt in a reactor with dry air. Oxygen is used 20% excess of that required for the complete combustion of sulphur to SO3. The efficiency of the reactor is such that only 30% of the sulphur converts to SO3 and the remaining goes to SOZ Reaction1: S+02SO3 Reaction2: S+02 502 Take basis as Ikmal of sulphur burnt a Calculate the product gas composition of resulting gaseous mixture in mole%. [10 marks] b Calculate the weight of the product gas per kg of the sulphur burnt. [10 marks
