Nitric oxide (NO) can be formed from nitrogen, hydrogen and oxygen in two steps. In the first step, nitrogen and hydrogen react to form ammonia: N2(9) + 3 H2(g) → 2 NH3(g) AH =-92. kJ In the second step, ammonia and oxygen react to form nitric oxide and water: 4 NH3(9) + 50,(9) → 4 NO(9) + 6H,0(9) AH =-905. kJ Calculate the net change in enthalpy for the formation of one mole of nitric oxide from nitrogen, hydrogen and oxygen from these reactions. Round your answer to the nearest kJ. ?
