Use Graham’s Law to calculate fast O2 gas will effuse compared to Cl2. SHOW YOUR WORK ON PAPER
O2 effuses 1.5 times faster than Cl2
O2 effuses 0.67 times as fast as Cl2
O2 effuses 2.2 times faster than Cl2
O2 effuses 0.45 times as fast as Cl2
Identify the factor that determines rates of diffusion and effusion for different molecules at a given temperature.
Size of the molecules
Polarity of the molecules
Temperature of the gas
Molar mass of the gas
Effusion and diffusion rates are inversely proportional to the square root of the molar mass of the gas.
True
False
Which is true regarding diffusion and effusion?
Both involve the movement of gas particles.
Diffusion is the movement of one substance through another, the gradual mixing of two substances.
Effusion is the movement of a gas through a tiny opening
Grahams law refers specifically to
the rate of diffusion
the rate of effusion
the temperature of gases
the partial and total pressures of gases in a sample.
