Question

Between CO and CO2 which diffuses faster ? and whats the reason ??

Answer 1

According to Graham's law,
The rate of diffusion is inversely proportional to the square root of molecular masses.

r1/r2=√M2/M1
CO/CO2=√44/28=√1.57=1.25
CO=1.25 CO2

It means CO diffuses 1.25 times the rate of diffusion of CO2.

The gas which has less molecular mass diffuses faster.
CO=28 g
CO2=44 g
As CO has less molecular weight, it diffuses faster.

So, CO diffuses faster
