CHEM 205 Lecture Notes - Phase Rule, Triple Point, Boltzmann Constant
Document Summary
0th law: absolute temperature (0k = no movement/vibrations) 1st law: conservation of energy - keeping track of energy changes and allow us to calculate the heat a reaction produces. 2nd law: why some rxns occur but others don"t by keeping track of changes of both enthalpy and entropy (system and surroundings) 3rd law: defines absolute entropy for a pure substance. Dalton"s law of partial pressure: p(total) = p1 + p2 + p3 Do not interact each other except for collisions (i. e. no repulsive/attractive forces) E(kinetic) = u = (f/2)rt where f is the degrees of freedom; 3 for monoatomic, 5 for diatomic. Degrees of freedom are based on translational and rotational. Van der waals equation: (p+an^2/v^2)(v-nb) = nrt: repulsive interaction (size effect): ig are assumed to have no volume but in reality gases take up some amount of volume. Virial equation of state: z = pv/nrt = 1 + b2p*p + b3p*p + where b2p,
