GRAHMS LAW

• • rate of effusion of a gas is inversely proportional to the square root of its molar mass
• • less mass = faster gas
• equation(s)

  rate = 1/sq root of molar mass

  (rate a/rate b) = (sq root of molar mass b/sq root of molar mass a)
• one with the higher rate goes on the the top for the rate a & b problem
