Calculate the relative rates of diffusion for
`.^(235)UF_(6)` and `.^(238)UF_(6)`.

Text Solution

Verified by Experts

According to Graham's law of diffusion
`(r_(1))/(r_(2)) = sqrt((M_(2))/(M_(1)))`
Since `M` wt of `.^(235)UF_(6)`
M .wt. of `.^(238)UF_(6) = 352`
`:. (r.^(235)UF_(6))/(r.^(238)UF_(6))=sqrt(352/349)=1.00043`
