Consider each of the following processes and determine if work is done by the system, work is done on the system or no work is done. N2 (g) → N2 (l) 2 Na (s) + 3 H2O (l) → 2 NaOH (aq)+ H2 (g) 2 NO (g) + O2 (g) → 2 NO2 (g) 2 CH3OH (l) + 3 O2 (g) → 2 CO2 (g) + 4 H2O (g) 4 NH3 (g) + 5 O2 (g) → 4 NO (g)+ 6 H2O (g)
