The enthalpy of reaction for the given above and any other given can be calculated through the equation,
Hrxn = H(product) - H(reactants)
From reliable sources, the values of H of the substances.
H(NO) = 90.25 kJ/mol
H(O2) = 0 kJ/mol
H(NO2) = 33.18 kJ/mol
Substituting the known values,
Hrxn = (2)(33.18 kJ/mol) - (2)(90.25 kJ/mol)
Simplifying,
Hrxn = -114.14 kJ
<em>ANSWER: -114.14 kJ</em>
