Unformatted text preview: C and 1 atm • A reaction in which reactants and products are all in their standard states are accompanied by a standard enthalpy ΔH ° • ΔH°f is equal to the enthalpy change when one mole of compound is formed from the elements in their standard states. REMEMBER: 1. Elements in their standard states can be omitted(ΔH°f = 0) 2. The coefficients of products and reactants have to be taken into account. Chapter 4.5 Bond Enthalpy - Not all bonds have the same strength. Instead of strength we could say Bond Energy or better bond enthalpy Bond Enthalpy: the heat energy ΔH required to break one mol of bonds ****It is always assumed that the reactants and products are in the gas phase ****Large #’s represent strong bonds Chapter 4.6 First Law of T...
