CH 101 Lecture Notes - Lecture 9: Chemical Energy, Gibbs Free Energy, Energy
Document Summary
Explain the principles of the 1st and 2nd laws of thermodynamics. Define enthalpy of a reaction abn relate it to bond energies. Describe thermodynamic driving force behind a reaction (gibbs free energy) Describe energy changes required to convert reactants to products. Study of energy and its transformations (triangle e) Considers difference in energy of reactants and products only (does not consider path) Can predict if a reaction is favorable, but not rate of reaction. The study of the rates and mechanisms of reactions. Deals with the path of the reaction and how fast or slow. Can predict if a reaction will occur quickly or slowly. Stored chemical potential energy, reacting it with a strong oxidizing agent, into kinetic energy. Energy : the capacity to do work(w) or transfer heat(q) Heat : form of energy that flows between two objects because of their difference in temperature. Other forms of energy : light, electrical, kinetic and potential(stored in bonds)
