Small amounts of NH3 and HCl(g) are released simultaneously at the opposite ends of a 2 metres long tube. At what point the formation of NH4Cl would start? (Either end of the tube can be used to tell the answer.)
The formation of
Graham's law of diffusion states that the rate of diffusion of a gas is inversely proportional to the square root of its molecular mass.
We can write the law as
#color(blue)(bar(ul(|color(white)(a/a)r_1/r_2 =sqrt(M_2/M_1)color(white)(a/a)|)))" "#
If Gas 1 is

So, the white ring will be formed at a distance of 0.8 m from the
