Document Summary
The first law of thermodynamics states that energy can be neither created not destroyed. The second law of thermodynamics implies that for every energy transaction, some energy is lost to the surroundings; this lost energy is nature"s heat tax. Spontaneous process: is one that occurs without ongoing outside intervention. Thermodynamics: study of the spontaneity of a reaction. Kinetics: study of the rate of a reaction (catalysts affect only the rate of a reaction, not the spontaneity) Second law of thermodynamics: for any spontaneous process, the entropy of the universe increases. Entropy (s): s = k lnw; k = 1. 38*10-23 j/k: proportional to the number of energetically equivalent ways in which the components of a system can be arranged, a measure of energy dispersal per unit temperature. Heat transfer and changes in the entropy of the surroundings. For a process to be spontaneous, the total entropy of the universe (system + surroundings) must increase.
