Sulfur dioxide, SO2(g), can react with oxygen to produce sulfur trioxide, SO3(g)

Question

Sulfur dioxide, SO2(g), can react with oxygen to produce sulfur trioxide, SO3(g), by the following reaction 2SO2(g) + O2(g) --> 2SO3(g). The standard enthalpies of formation for SO2(g) and SO3(g) are -296.8 kJ/mol and -395.7 kJ/mol respectively.

Calculate the amount of energy in the form of heat that is produced when a volume 1.12 L of SO2(g) is converted to 1.12 L of SO3(g) according to this process at a constant pressure and temperature of 1.00 bar and 25.0C. Assume ideal gas behaviour.

Answer in kJ.
