Dalton's law
Total pressure exerted by a gaseous mixture is the sum of the partial pressures of each of its gases |
P(total) = P₁ + P₂ + P₃...
|
|
|
Grahams law
Average speed of molecules of a pure gas is inversely proportional to the square root of the mass of the gas molecule |
(v₁/v₂) = √m₁ /√m₂
|
|
|
Effusion
|
The spreading of gas from high pressure to very low pressure (through a pinhole)
|
|
|
Rates of effusion
|
(effusion rate₁/ effusion rate₂) = √M₂ /√M₁
M = molecular weight |
|
|
Diffusion
|
The spreading of one gas into another gas or into empty space
|
|
|
Real vs. Ideal
|
V (real) > V (ideal)
P (real) < P (ideal) |
|
|
Thermodynamics
|
The balance of reactants and products after they have achieved equilibrium
|
|
|
Activation energy
|
The threshold energy required in a collision to create new molecules
|
|
|
Elementary reaction
Occurs in a single step Rate Law |
aA + bB → cC + dD
rate(forward) = kf [A]^α[B]^β α + β = overall order of the reaction α = a β = b |
|
|
Intermediates
|
Species that are products of one reaction and reactants of a later reaction in a reaction chain

Chemical equilibrium
|
The forward reaction rate equals the reverse reaction rate
|
|
|
Le Chatelier's principle
|
When a system at equilibrium is stresses, the system will shift in a direction that will reduce stress
