Graham’s Law

Answer 38

I’m the rate of effusion of a gas, which is the amount of gas that moves through a hole in a given amount of time, is inversely proportional to the square root of its molar mass.

Thgrahams law of effusion

Answer 41

The rates of effusion (v) of two gases at the same temperature and pressure are inversely proportional to the square root of their densities (P) or molar mass (M).
