Knowledge Statements

1. The extent to which a reaction will occur is determined by the free energy difference between reactants and products.
2. The equilibrium constant for a reaction is a function of the free energy change between reactants and products.
3. The rate at which a reaction will occur is determined by the energy levels of the intermediates between reactants and products as well as the relative concentrations of reactants and products.
4. At equilibrium, the forward and backward rates of a reaction are equal.
5. The energy required to overcome a reaction's activation energies typically come from the thermal energy of the environment.
6. Activation energies arise primarily from the energy required to break bonds.
7. A system displaced from equilibrium will return to equilibrium.
