WebSo let's say it's 100 minus 50, which would be positive 50 kilojoules per mole. So on our diagram if we represent Delta E, that would be this difference here on the energy profile. And once again, Delta E is equal to the change in the enthalpy Delta H for the reaction. So Delta H for this hypothetical reaction is positive 50 kilojoules per mole. WebNow do the calculation: Hess's Law says that the enthalpy changes on the two routes are the same. That means that: ΔH - 3267 = 6 (-394) + 3 (-286) Rearranging and solving: ΔH = 3267 + 6 (-394) + 3 (-286) ΔH = +45 kJ … methodist hospital memphis patient portal
