The gas stream from a sulfur burner consists of 15 mol% SO2, 20 mol% O2, and 65 mol% N2. The gas stream at atmospheric pressure and 400 C enters the catalytic converter where 86% of the SO2 is oxidized to SO3. Assuming that 1 mol of gas enters, how much heat must be removed from the converter so that the gases produced leave at 500C? Change enthalpy for entropy.
