Combustion of methane showing … WebThe enthalpy of a bond is the enthalpy change that occurs when 1 mole of a particular bond is broken in the gas phase. Since energy is required to break a chemical bond, bond enthalpies are always reported as positive values. For any chemical reaction, the estimated change in enthalpy is the sum of the bond enthalpies of the bonds broken minus ... WebSo the summation of the bond enthalpies of the bonds that are broken is going to be a positive value. And since it takes energy to break bonds, energy is given off when bonds form. So next, we're gonna sum the bond enthalpies of the bonds that are formed. And notice we have this negative sign in here because this energy is given off. javascript print image from url
