Document Summary
Ideal gas law: pv = nrt: pressure, volume, number (moles), . 08206, temp (k) Law of mass action: kc/p = ccdd / bbaa: used for concentration/pressure of gas molec in equilibrium. Vmp = 2kbt/m = 2rt/m most probable velocity/speed: m = kg (must convert from g/mol to just kg (use avo #) Vrms = 3kbt/m = 3rt/m root mean square speed: m = kg/mol. (per mole) = 3/2 rt average kinetic energy. Kw = [h3o+][oh : auto-ionization equilibrium constant. Kw = kakb: by association acid base, can use this to find ka or kb, kw = 1. 0 10-14 (@ 25 c) Pkw = ph + poh: when neutral ph = poh. Ka = [h3o+][a ]/[ha: acid equilibrium constant. Kb = [oh ][ha]/[a : base equilibrium constant. Ph = -log[h3o+: ph value (needs concentration of h3o+) Poh = -log[oh : poh value (needs concentration of oh )
