Ammonia can be obtained according to reaction (b) or (c). Which of the following is correct regardin — Thermodynamics and Thermochemistry Chemistry Question

💡 Solution & Explanation

Both reactions inherently produce 2 moles of $\text{NH}_3$. Reaction (b) is highly endothermic ($+241.35\text{ kcal}$) compared to reaction (c) ($+34.18\text{ kcal}$). Therefore, strictly more heat is needed for reaction (b) to yield the exact same amount of product.
