Which of the reaction will generate the greatest amount of energy on a total mass basis of reactants — Thermodynamics and Thermochemistry Chemistry Question

💡 Solution & Explanation

Calculate energy per gram of the total reactants: For $\text{H}_2-\text{O}_2$, $483.636 / (4 + 32) = 13.43\text{ kJ/g}$. For $\text{H}_2-\text{O}_3$, $868.2 / (6 + 48) = 16.08\text{ kJ/g}$. For $\text{H}_2-\text{H}_2\text{O}_2$, $347.33 / (2 + 34) = 9.65\text{ kJ/g}$. The maximum yield is with $\text{H}_2-\text{O}_3$.
