Bond enthalpy vs enthalpy of formation

WebJan 15, 2016 · Re: Enthalpy vs Standard Enthalpy of Formation. Enthalpy is the total heat content of a system. At systems with constant pressure, the heat flow of a process is equal to the change in enthalpy for a reaction. In other words, at constant pressure it represents how much energy/heat was absorbed/released by the reaction. WebBond enthalpies Energy is required to break a covalent bond between two atoms to overcome the attractive force. Bond breaking is an endothermic process. The opposite is true if we want to...
