Document Summary

N = 1. 5 mol qrxn = -qcal h = e + p v p v = nrt | h| > | e| boiling point problem: svap = h vap / tboil rate laws + equations provided on final. 3 problems: thermochem/dynamics intermolecular forces as part of problems. 1 problem: given question, t/f or choose from given expect 8-9 problems. Defines energy of colliding particles; require certain level/threshold at which point particles collide may proceed) Structure & relative orientation of reacting particles (a-x + b a-b + x) collision model. Particles collide 24/7 but very few are productive. If we assume all particles are productive, the fastest is rate of diffusion (that depends on medium) will define upperlimit. Rate of vibration - define upper limit of unimolecular reaction if it"s a bond breaking process average rate = change in concentration of reactants divided by time period (t2 - t1)
