Transcribed Image Text:In chemical reactions, heat is converted into chemical energy (the potential energy stored
in chemical bonds) or vice versa. Bond energy is the energy required to break one mole of
the bond in the gas phase. Since it takes energy to break a bond, bond energies are
always positive. Conversely, energy is released when bonds are formed. Thus, the
enthalpy change for a reaction can be approximated from
