Which oxidizing agent will generate the greatest amount of energy for 1 mole of (g)? — Thermodynamics and Thermochemistry Chemistry Question

💡 Solution & Explanation

Energy per mole of $H_2$:<br>For $O_2$: 483.636 / 2 = 241.818 kJ/mol.<br>For $O_3$: 868.2 / 3 = 289.4 kJ/mol.<br>For $H_2O_2$: 347.33 / 1 = 347.33 kJ/mol.<br>Thus, $H_2O_2$ releases the maximum energy per mole of $H_2$.
