Document Summary

Any spontaneous process increases the disorger of the universe: note: processes that don"t increase the disorder of the universe require work to be done in opposition to the disprder. (often impossible) Spontaneus: not requiring an outside source of energy to proceed: ex) diamond to graphite spontan, but bonds so stable almost never happens. State function does not depend on the pathway the system took kto reach its current state: therefore cant measure directly. No delta r. s = cuz we know absolute values of entropy of individual reactants and products. Delta l. s = we finna calculate the change in entropy that occurs when the reactants rearrange into the prods. Gibbs free energy: amount of energy in a system that is available to do useful work: state function does not depend on the pathway the system took kto reach its current state.
