Document Summary

2nd law of thermodynamics --> for any spontaneous process, the entropy of the universe increases. 3rd law of thermodynamics --> the entropy of a perfect crystal at absolute zero is zero. Entropy --> a thermodynamic function that is proportional to the number of energetically equivalent ways to arrange the components of a system to achieve a particular state; Measure of energy randomization or energy dispersal in a system irreversible reaction --> a reaction that does not achieve the theoretical limit of available free energy. Lechatelier"s principle --> -if stress is applied at equilibrium, the system will shift in the direction which helps elevate the stress. Microstates --> the specific way in which we can arrange the energy of the system. Reversible reaction --> a reaction that achieves the theoretical limit with respect to free energy and will change direction upon an infinitesimally small change in a variable related to the reaction.
