Calcolatore Quoziente di Reazione — Formula

Heat of Reaction per Mole

Formula

ΔH_rxn = q / n

Where:

  • ΔH_rxn = heat of reaction per mole (kJ/mol)
  • q = total heat measured (kJ), negative for exothermic
  • n = moles of limiting reagent

    • This converts calorimetry data into a molar enthalpy value for the reaction.

    Esempio Risolto

    A reaction releases 50 kJ of heat using 0.1 mol of limiting reagent.

    1. ΔH_rxn = q / n
    2. ΔH_rxn = -50 / 0.1
    3. ΔH_rxn = -500 kJ/mol
