Question

Rate of diffusion of hydrogen is :
(1) Half of He
(2) 1.4 times of He
(3) Double than He (4) four times of He​

Answer 1

Answer:

rate of diffusion is inversely proportional to square root of molecular weight

r h / r he = M he / M h

r h /r he = 4 /2 =2

r h = 2 r he

option 3 is correct
