Question

How much heat is transferred per mole of NH₃(g)formed in the reaction shown below? N₂(g)+ 3 H₂(g)→ 2 NH₃(g)ΔH° = - 92.2 kJ

Quizplus · Accepted Answer

According to the balanced equation, 2 moles of NH₃(g) are formed for every 92.2 kJ of heat released. Therefore, the amount of heat transferred per mole of NH₃(g) formed is equal to: 92.2 kJ / 2 moles = 46.1 kJ/mol Therefore, the best answer is B, with an explanation that uses the balanced equation to calculate the amount of heat transferred per mole of product formed.
