Document Summary

2. 1 kinetics and thermodynamics of simple chemical processes. Chemical thermodynamics the steps which deal with the changes in energy that take place when processes such as chemical reactions occur; controls the extent to which a reaction goes to completion. Chemical kinetics the steps which concern the velocity or rate at which the reaction occurs; the speed of the reaction goes to completion. Thermodynamic control a transformation that yields the most stable products. Kinetic control a reaction in which the product obtained is the one formed fastest: note: thermodynamic control and kinetic control can apply to the same reaction, but does not have to. Gi(cid:271)(cid:271)"s free e(cid:374)ergy the energy that has been released or taken up by a reaction (cid:3032)(cid:3044)=[(cid:1829)][(cid:1830)] No: h enthalpy; the heat absorbed or released at constant pressure during the course of the reaction; mostly talking about differences in bond energy between products and reactants (bond-dissociation energies) H exothermic: s entropy; the amount of disorder.
