The preparation of NO₂(g) from N₂(g) and O₂(g) is an endothermic reaction:

The enthalpy change of reaction for the balanced equation (with lowest whole-number coefficients) is ΔH = 67.7 kJ. If 2.50 × 10² mL N₂(g) at 100.^οC and 3.50 atm and 4.50 × 10² mL O₂(g) at 100.^οC and 3.50 atm are mixed, what amount of heat is necessary to synthesize the maximum yield of NO₂(g)?
