Document Summary
Thermodynamics tells us which direction a reaction will go (e. g. at room temperature and standard pressure, carbon is stable as graphite) Kinetics can tell us how quickly it will get there (e. g. a diamond will not convert to graphite during your lifetime) (thermodyamics will be considered later in this course. ) Reading: petrucci, harwood, herring, madura and bissonnette, chapter 14. Problem set: chapter 14 questions 7, 12, 14, 23a, 24, 41, 53, 70. Suggested problems: chapter 14, questions 56, 57, 60, 62, 87. Aims of chemical kinetics: describing chemical reaction rates: definition of rate of reaction . How rates can be measured. how rates depend on concentrations. An important aspect of chemistry is how fast (or slow) reactions are. The reaction of sugar with oxygen is very favourable. The reaction of gasoline with oxygen is very favourable. It is usually slow at room temperature. a spark can make the reaction occur very rapidly. Expressed as the rate of change of concentrations.
