Assuming that the gases are ideal calculate the amount of work done (in joules) in each of the following reactions. In each case, is the work done on or by the system? (a) The oxidation of one mole of HCl(g) at 2000C. 4HCl(g) + O2(g)  2Cl2(g) + 2H2O(g)
(b) The decomposition of one mole of nitric oxide (an air pollutant) at 3000C. 2NO(g)  N2(g) + O2(g)
