The gas stream from a sulfur burner is composed of 15-mol-% SO2, 20-mol-% 02, and 65-mol-% N2.

Question:

The gas stream from a sulfur burner is composed of 15-mol-% SO2, 20-mol-% 02, and 65-mol-% N2. This gas stream at 1 bar and 480°C enters a catalytic converter, where the SO2 is further oxidized to SO3. Assuming that the reaction reaches equilibrium, how much heat must be removed from the converter to maintain isothermal conditions? Base your answer on 1 mol of entering gas.
