Question

When a gas is diffusing through air in a diffusion channel, Che diffusion rate is the number of gas atoms per second diffusing from one end of the channel to the other end. The faster the atoms move, the greater is the diffusion rate, so the diffusion rate is proportional to the rms speed of the atoms. The atomic mass of ideal gas A is 2 u, and that of ideal gas 3 is 3 u. For diffusion through the same channel under the same conditions, find the ratio of the diffusion rate of gas A to the diffusion rate of gas B. RpJ Rq = Number Units

Explanation / Answer

The atomic mass of ideal gas A is 2 u, and that of ideal gas B is 4 u.; diffusion rate is inversely related to squre root of atomic mass; dA/dB=sqrt(atomic mass of B/atomic mass of A); =sqrt(4u/2u); =sqrt 2; =1.414; conclusion the lesser the atomic mass diffuses faster than greater atomic mas..
