The gas phase reaction oxidation of SO₂ to SO₃ is carried out at a pressure of 1 bar with 20% excess air in an adiabatic reactor. The reactants enter at 25 °C and equilibrium is obtained at the exit of the reactor.

a) Write the balanced equation for the formation of one mole of sulfur trioxide. 

b) What is the heat of reaction of the equation in part (a)? 

c) Determine the composition and the temperature of the product stream from the reactor. 

The heat capacities of the components are given by the equation.
