Sulfur dioxide, SO2(g), can react with oxygen to produce sulfur trioxide, SO3(g), by the following reaction2SO2(g) + O2(g) -> 2SO3(g)
The standard enthalpies of formation for SO2(g) and SO3(g) are
Delta H ( SO2 (g) ) = -296.8 KJ/Mol
Delata H ( SO3 (g) = -395.7 Kg?mol
Calculate the amount of energy in the form of heat that is produced when a volume of 1.25 L of SO2(g) is converted to 1.25 L of SO3(g) according to this process at a constant pressure and temperature of 1.00 atm and 25.0 °C. Assume ideal gas behavior.
