Unformatted text preview: Chemical Thermodynamics Chp. 10 Enthalpy H chp. 9 Entropy S chp. 10 Gibbs Free Energy G chp. 10 1 st Law of Thermodynamics the energy of the universe is constant. chp. 9 2 nd Law of Thermodynamics the entropy of the universe is increasing. chp. 10 3 rd Law of Thermodynamics the entropy of a crystalline substance approaches zero as the absolute temperature approaches zero. chp. 10 Thermodynamics study of energy changes associated with chemical or physical processes. Spontaneous occurs without any ongoing outside intervention. Spontaneous reactions may be fast or slow. Many, but not all, spontaneous reactions are exothermic. Spontaneity Chp. 10.2 A process may be spontaneous at one temperature and non- spontaneous at another temperature. Spontaneity Chp. 10.2 Reversible Processes- System and surroundings can be restored to original state by exactly reversing the process. Reversibility Chp. 10.2 Spontaneous processes are irreversible....
