Question

State grahams law of diffusion?​

Answer 1

Answer:

Hey mate

GRAHAMS LAW : It states that the rate of diffusion of a gas is inversely propotional to the square root of it's density .

Explanation:

let us consider two gases A and B diffusing into one another . let P1 and P2 be their densities and V1 and V2 their respective r.m.s. velocities. pressure exerted by gas A =

P1 = 1/3 p1 V1^2

and pressure exerted by gas B =

P2 = 1/3 p2 V2^2

when steady state of diffusion is reached

P1 = P2

1/3 p1 V1^2 = 1/3 p2 V2^2

V1^2/V2^2 = p2/ p1

HOPE IT IS HELP FULL

THANK U GUYS.

Answer 2

It states that the rates of diffusion of gases are inversely proportional to the square roots of their densities under similar conditions of temperature and pressure.
