CHEM 1A Lecture Notes - Lecture 14: Total Pressure, Pauli Exclusion Principle, Partial Pressure
Document Summary
The more ways something can happen, the more likely it is. Multiplicity w = # of microscopic arrangements that give a certain outcome. For a gaseous mixture, pv = n1m1 = (n1+n2) rt x,1> + n2m2 = (3kbt) / m, but trajectories are greatly complicated by the fact that these molecules exert forces on each other (they interact) At a close range, molecules tug and push on each other. These imf"s make condensed phases much more interesting, and more complicated. Some basic reasons that atoms bond to form molecules: electrons attract nuclei, repel each other, and obey the laws of quantum mechanics. Pauli principle prevents electron clouds from overlapping.
