Nitrogen oxide (NO) has been found to be a key component in many biological processes. It also can react with oxygen to give the brown gas NO2. When one mole of NO reacts with oxygen, 57.0 kJ of heat are evolved. How many grams of nitrogen oxide must react with an excess of oxygen to liberate 10 kJ of heat? NO(g) + ½O2(g) → NO2(g) ΔH = –57.0 kJ
