Limited enrollment course with a more rigorous treatment of material covered in course 2B. Students completing course 2BH can continue with course 2CH or 2C.
- Thermochemistry is the study of the energy and heat associated with chemical reactions and/or physical transformations. A reaction may release or absorb energy, and a phase change may do the same, such as in melting and boiling. Chemical thermodynamics studies the nature of the role of entropy in the process of chemical reactions and provided the bulk of expansion and knowledge of the field.
- Macroscopic quantities of matter can exist in only one of three states: Gas, Liquid or Solid. The following are not states of matter: electricity, gels, powders, plasmas, supercritical fluids or your mother's apple pie. Only two aspects determine the state of matter for a specific system/chemical: 1) The (intermolecular) forces within the sample and 2) the conditions outside the sample (e.g. temperature, pressure etc).
- Chemical equilibrium is a state in which the rate of the forward reaction equals the rate of the backward reaction. In other words, there is no net change in concentrations of reactants and products. This kind of equilibrium is also called dynamic equilibrium and can be used in a wide range of processes including both chemical and physical changes.
