Question

What mass of nitrogen must burn in excess oxygen to produce 18.0 kJ of heat, given the following thermochemical equation? N₂ (g) + O₂ (g)→2 NO (g) D H = +1.80×10² kJ

Quizplus · Accepted Answer

The given thermochemical equation shows that the reaction is endothermic (ΔH is positive), meaning heat is absorbed, not released.
