PLSS STEP BY STEP SOLUTION! :)
The first chemical step in making sulfuric acid from elemental sulfur is burning the sulfur (completely) to form SO2. Calculate the temperature of the gas leaving the burner based on the following: the burner operates adiabatically, sulfur enters as liquid at 140C, and excess air (79% mol N2, 21% O2) enters at 25C; H (S(), 140C S(s,rh), 25C) = -5.07 kJmol-1; the outlet gas contains 9.5 mol % SO2; other data required are given in table.
