When 3.52 g ammonia gas is oxidized over a platinum catalyst to form nitrogen monoxide gas and water, 60.4 kJ of heat are released. Develop a complete thermochemical equation for this process, using smallest possible coefficients. Then calculate the enthalpy change when 2 moles of nitrogen monoxide react with water to form ammonia and 2.5 moles of oxygen.

thank you I really do not understand this
