Question

Find the ratio of rates of diffusion of hydrogen and oxygen​

Answer 1

1:4

Explanation:

Diffusion is known as the movement of a substance from an area of high concentration to an area of low concentration. Diffusion is seen in liquids and gases because their particles move randomly from place to place. Rate of diffusion of a gas is inversely related to the square root of molar mass of a gas.

r1r2=M2M1−−−−√

r1= Rate of diffusion of oxygen

r2= Rate of diffusion of hydrogen

M1= Molecular weight of oxygen

M2= Molecular weight of hydrogen

Complete Step By Step Answer:

M1=32g of O2

M2=2g of H2

Substituting the values in the formula we get,

r1r2=232−−−√

r1r2=116−−−√

r1r2=14

Therefore, the ratio of diffusion rate of oxygen to hydrogen is 1:4 .

Hence, the correct option is (a) 1:4 .
