R1.2.1 Average Bond Enthalpy Calculations [SL IB Chemistry]

Описание к видео R1.2.1 Average Bond Enthalpy Calculations [SL IB Chemistry]

If you know the energy required to break all the bonds in the reactants AND make all the bonds in the products you can work out the overall energy change for the reaction. Assume STP and this only works if everything involved is a gas. (Else the energy you put in may cause evaporation, boiling, hydrogen-bond breaking etc).
