Graham’s law says that gas will effuse at a rate that is inversely proportional to the square root of its molecular mass, MM. Expressed mathematically:
rate1/rate2 = √MM2/MM1
- Under the same conditions of temperature and pressure, how many times faster will hydrogen effuse compared to carbon dioxide?
- If the carbon dioxide in Problem 1 takes 32 seconds to effuse, how long will the hydrogen take?
- what is the relative rate of diffusion of NH3 compared to He? Does NH3 effuse faster or slower than He?
