I have the answer but I'm not sure how to get there.
Use the standard reaction enthalpies given below to determine delta H degree _rxn for the following reaction: I NO(g) + O(g) rightarrow NO_2(g) delta H degree _rxn = ? II NO(g) + O_3(g) rightarrow NO_2(g) + O_2(g) delta H degree _rxn = -198.9 kJ III 2 O_3(g) rightarrow 3 O_2(g) delta H degree _rxn = -284.6 kJ IV O_2(g) rightarrow 2 O(g) delta H degree _rxn = +495.0kJ A. +11.5 kJ B. -978.5 kJ C. -303.8 kJ D. -588.4 kJ E. -93.7 kJ
