Question

Out of N2 and CO which will diffuse at faster rate and why?​

Answer 1

Answer:

According to Graham's law of diffusion, the rate of diffusion or movement of gas is inversely proportional to the square root of it's molecular weight. Among H2 , O2 , CO, and N2 , the gas with least mass is hydrogen. So hydrogen diffuses faster whereas oxygen takes long time to diffuse.

Answer 2

Question:

Out of $N_{2}$ and $CO$ which will diffuse at a faster rate and why?

Answer:

Both will have same rate.

Explanation:

$\bf{r = \sqrt{\frac{1}{M_{m}}}}$

$\bf{M_{m}}$ of $\bf{N_{2}}$ = 28

$\bf{M_{m}}$ of $\bf{CO}$ = 12+16 = 28
