Given the reaction shown below, calculate:

(a) The amount of NO2, in grams, generated from reactants if 300.23 kJ of heat energy is released during the course of the reacton.

(b) The heat energy released if 33.23 grams of O2 is consumed in the reaction.

2 NO(g) + O2(g) „_ 2 NO2(g) ƒ´Hrxn = ¡V114.2 kJ
