Nitrogen monoxide reacts with oxygen gas to give nitrogen dioxide. The standard heat of reaction, for the reaction as written, is -114.1 kJ; it is exothermic. The reaction is 2 NO(g) + O2 (g) => 2 NO2 (g) If 2.01 grams of nitrogen monoxide is consumed in a reaction, what amount of heat, in kJ, is generated?

2NO + O2 ---> 2NO2, delta H = -114.1 kJ 

2.01 g NO x (1 mole NO / 30.0 g NO) x (-114.1 kJ / 2 moles NO) = 3.82 kJ of heat generated
