UCB chem1a lec 25 What a mess: energy dispersal

can be 'bond enthalpies' or 'heats of formation'
H${}^0_{RxN}$ = $- \Sigma $(BE of products) $ + \Sigma$(BondEnergy of reactants)
H${}^0_{RxN}$ = H${}^0_f(ormation)(products)$ - H${}^0_f$(reactants)
$\Delta$S${}^0_{rxn} = \Sigma$S${}^0$(products) $+ \Sigma$S${}^0$(reactants)
