Concept explainers
Interpretation:
Four different gases are there in four containers. The gas with fastest rate of effusion is to be found out.
Concept introduction:
It is based on Graham’s Law of effusion. According to it,
Answer to Problem 4STP
Explanation of Solution
The rate of effusion is inversely proportional to molar mass, therefore the gas having least molar mass will have fastest rate of effusion.
Therefore, helium gas will have fastest rate of effusion.
As helium gas has fastest rate of effusion, option B is correct and rest are incorrect.
