Graham's Law of Diffusion

Remember, Write the law with subscript of gases and always show rate of diffusion ratio with subscripts. SIG FIGS - TWO PLACES AFTER DECIMAL

1. What is the relative rate of diffusion of carbon dioxide gas to nitrogen gas?

2. How many times faster is hydrogen gas to chlorine gas (both gas are in elemental form)?

3. What is the relative rate of diffusion of nitrogen dioxide and ammonia gas?

Answer: 1) rN2/rCO2 =1.25 or rCO2/rN2=0.80
2) rH2/rCl2 = 5.96
3) rNH3/rNO2 = 1.64 or rNO2/rNH3N2=0.61
