Gas Laws
Boyle's Law
pressure is inversely proportional to volume
Charles' Law
volume is directly proportional to temperature
Avogadro's Law
volume is directly proportional to number of moles
Amontons' Law
pressure is directly proportional to temperature
Ideal Gas Law
PV=nRT
R = 0.0821 L atm/mol K
Combined Gas Law
(P1 V1)/(n1 T1 )=(P2 V2)/(n2 T2 )
Density
d = P MW/RT
Dalton's Law
:star2: The total pressure of a mixture of gases is equal to the sum of the pressures exerted by the individual gases
Ptotal = P1 + P2 + P3 + ...
Partial pressure is the product of mole fraction and total pressure
Mole fraction is the product of the moles of individual gas and the total number of moles
Pn = Xn Ptotal
Graham's Law
the rate of
effusion
or
diffusion
of a gas is inversely proportional to the square root of its molar mass
Non-ideal behavior
If the pressure is
very
high, or the volume is
very
low, or the temperature is
very
high, the gas may not behave ideally
Use van der Waals equation
Pressure is the ratio of force to surface area
P = F/a
