If 480 IbO2 is added to 680 IbH2S and the reaction is complete, the reactants enter at 300°F
and the products leave at 100°F. Calculate the heat evolved or absorbed from the reactor
during the reaction in Btu.
Given that:The standard heats of formationĤºr (KJ/gmol): H2O (g) = -241.83,
H2O (1) = -285.84, H2S (g) = -20.15,
1Kg=2.2 Ib, 1 Ib = 454 gm, 1Cal = 4.2J, 1 Btu = 252 Cal
Hint: take reference temperature 77 °F.
