Mole fraction
Miles/total moles
Molality
Moles solute/mass solvent (kg)
Mass %
Mass solute/ mass solution *100
Volume %
Volume solute / volume solution *100
Chemical kinetics
Tells how fast a reaction occurs
Mechanism
Tells the details of the reaction
rate
Rate = change in conc product / time interval
+if finding product formed
-if finding rate of which it depletes
Rate equations describes
Relation between rate or Chem reaction and concentration of reactant (rate law)
K =
rate (exp) / conc A * conc B
First order reaction 1/2 life constant
0.693
Kt =
Ln conc A o / conc A t
Unimolecular
Rate = k [cl2]
Bimolecular
Rate = k [cl2] [h2]
Termolecular
Rate = k [cl2] [h2] [c]
Osmotic pressure
II = n solute / V solution (RT)
II = MRT
Second order reaction
(1/[a]t) - (1/[a]o) = kt
