The given question is incomplete. The complete question is:
Which molecule would diffuse faster [tex]SO_2[/tex], or [tex]SO_3[/tex],? Explain your reasoning.
Answer: [tex]SO_2[/tex] will diffuse faster as it has low molecuklar weight.
Explanation:
From Graham's law of diffusion rates, the rate of diffusion of a gas is inversely proportional to the square root of its molar mass.
[tex]Rate\propto \sqrt\frac{1}{M}[/tex]
or [tex]\frac{Rate_1}{Rate_2}\propto \sqrt\frac{M_2}{M_1}[/tex]
Molecular mass of [tex]SO_2[/tex] is 64 g/mol and Molecular mass of [tex]SO_3[/tex] is 80 g/mol
Thus as molecular mass of is less , it will diffuse faster.
