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 ... WebFor example, the bond enthalpy for a carbon-carbon single bond is about 348 kilojoules per mole. You might see a different value, if you look in a different textbook. However, we're gonna go with 348 kilojoules per mole for our calculation. And we're gonna multiply this by one mole of carbon-carbon single bonds.
