Unformatted text preview: Chapter 17 Lecture 1 Review of thermodynamics q = heat flow H = qp = Enthalpy W = the engineers can have it. We fixed it so that for any chemical reaction, the energy is transferred as heat. A + B C + D H = kJ Enthalpy is about kinetic energy of molecules. System Surroundings Endothermic Exothermic This time we did not lie in CHEM 1, but we only told half the truth. Besides Enthalpy (Kinetic motion) There is Entropy, arrangements, or order Entropy S What is entropy like? Your Room "Messy" "Clean" Equations about arrangements: S = k ln W Lot of possibilities appear by just one motion. S= ...
