A mixture of gaseous disulfur difluoride, dinitrogen tetrafluoride, and sulfur tetrafluoride is placed in an effusion apparatus.
(a) Rank the gases in order of increasing effusion rate.
Effusion is a process where a gas escapes from a container through a very tiny hole.
The rate of effusion of a gas decreases as its molar mass increases.
This is represented by the following relation:
