# What is the enthalpy associated with the formation of two moles of NO(g)?

${N}_{2} \left(g\right) + {O}_{2} \left(g\right) \rightarrow 2 N O + \Delta$
We know the molar quantity of dinitrogen gas, $\frac{13.7 \cdot g}{28.01 \cdot g \cdot m o {l}^{-} 1}$. We do not know the thermodynamic parameters of the question. $\Delta H$ should have been quoted with the question.........Once we have $\Delta {H}_{\text{rxn}}^{\circ}$ we can assess the value for the given molar quantity.
