Ratio of molecular weights of A and B is (4)/(25) then ratio of rates of diffusion will be

Correct answer: B. 5: 2 According to Graham's rule array l (r_1)/(r_2) = (M_2)/(M_1) or (r_1)/(r_2) = (25)/(4) =(5)/(2) array Hence ratio of diffusion is 5: 2

Ratio of molecular weights of A and B is (4)/(25) then ratio of...

Ratio of molecular weights of

A

and

B

\frac{4}{25}

then ratio of rates of diffusion will be

Options

A $5: 1$
B $5: 2$
C $25: 3$
D $25: 4$

Correct answer

B. $5: 2$

Step-by-step solution

According to Graham's rule

\begin{array}{l}\frac{r_1}{r_2} =\sqrt{\frac{M_2}{M_1}} \\ \text{or } \frac{r_1}{r_2} =\sqrt{\frac{25}{4}} \\ \Rightarrow =\frac{5}{2}\end{array}

Hence ratio of diffusion is

5: 2
