The rate of effusion for chlorine gas is much higher than that of nitrogen gas.
This can be seen in the table below.
Which compares the measured rates for both gases at room temperature and atmospheric pressure.
Table: The table shows that a sample size of chlorine will take about 5 times as long to effuse as a sample size of nitrogen.
This means that for a gas such as chlorine, it would take about three times the time to effuse out of an opening than with nitrogen.
The following table shows how long it will take (in seconds) for different sample sizes of each type of gas to diffuse through one square centimetre.
The following table also includes calculated values for both gases at room temperature.
Atmospheric pressure, assuming they are all equal in mass and have equal diffusion coefficients.
This is done so that data can be compared between the two types on a consistent basis.
At low pressures or high temperatures, however, these factors may not hold true .
Due to changes in density or viscosity which affect individual molecular speeds.
