How to solve for bond energy
WebEnthalpy values use the mean bond energy which is an average over different molecules. We can use the mean bond energy to calculate the ΔH of a reaction by using the formula: ΔH = Σ bond energies broken - Σ bond energies made. You can only use bond enthalpies to calculate ∆H when all substances are in the gas phase. WebWe can apply bond energy values to determine the enthalpy of a compound’s formation, ΔH f Δ H f, which can be roughly approximated by simply adding tabulated values for the …
