The oxidation of NH3 (g) to NO (g) in the Ostwald process must be very carefully controlled in terms of temperature, pressure, and contact time with the catalyst. this is because the oxidation of NH3 (g) can yeild any one of the products N2(g), N20 (g), NO (g), and NO2 (g), depending on conditions. Show that oxidation of NH3 (g) to N2 (g) is the most exothermic of the four possible reactions.
