Interpretation:
The ratio of diffusion rates for carbon monoxide and carbon dioxide needs to be determined.
Concept introduction:
According to the Graham’s law of effusion, rate of effusion of any gas is always inversely proportional to the square root of the mass of gaseous particles. The mathematical expression for this law is:
In terms of time for gases; we can write as:
Answer to Problem 2PP
Explanation of Solution
Carbon monoxide and carbon dioxide gases have different rate of diffusion.
The ratio of rate of effusion of two gases can be calculated as follows:
Molar mass of CO = 28 g/mol
Molar mass of CO2 = 44 g/mol
Plug the values in the equation:
