Answer 1

$\textbf{\underline{\underline{ANSWER:-}}}$

The ratio is 28:17

According to kinetic theory , the speeds of the molecules are inversely proportional to the square root of their molecular mass. So the speed of H2 molecule is √8 times greater than the speed of O2 molecule at the same temperature.

Also there are twice as many as H2 molecules . So escaping molecule is 2√8 times as likely to be a H2 molecule , as an O2 molecule. Thus 5.666 times as H2 molecules will escape as O2 molecules.

The fraction of hydrogen molecules lost would be

(1/4)*(5.66/6.66)

The fraction of oxygen

molecules lost would be

(1/4)*(1/6.66)

You would lose 21.2% of H2 molecules and only 3.75% of O2 molecules.

So in the remaining mixture, you would have

(2*78.8%)/(1*96.25%)=1.64 times as many H2 molecules as O2 molecules.

Now , comparing this with given answer.

28/17=1.674

(The value is closer)
