Assuming the gases are ideal, consider the work done on the system in each of the following reactions: a) The conversion of one mole of brown nitrogen dioxide into colorless dinitrogen tetroxide at 30.0◦C: 2 NO2(g) → N2O4(g) b) The decomposition of one mole of an air pollutant, nitric oxide, at 300◦C: 2 NO(g) → N2(g) + O2(g) Calculate the work done on (a) followed by the work done on (b).
