Me dont just comment for points i actually need order the relative rate of diffusion of the following gases from slowest to fastest. 1. 1                                     ar 2. 2                                     ne 3. 3                                   n 4. 4                                     kr

Kr < Ar < Ne < N (N is fastest and Kr is slowest)

Explanation:

According to graham law of diffusion, rate of diffusion of a gas is inversely proportional to the square root of molar mass of the gas.

Where R is rate of diffusion and M is molar mass

Molar masses of given gases are - Ar(40 g/mol), Ne(20 g/mol), N(14 g/mol) and Kr(84 g/mol)

So molar mass order : Kr > Ar > Ne > N

Hence rate of diffusion order: Kr < Ar < Ne < N (N is fastest and Kr is slowest)

i think so it’s will be b yes i believe its
