Equal moles of hydrogen () and oxygen () gases are placed in a container with a pin-hole. What exact — States of Matter and Gaseous State Chemistry Question

💡 Solution & Explanation

Rate ratio $r_{H2}/r_{O2} = \sqrt{M_{O2}/M_{H2}} = \sqrt{32/2} = 4$. This means $H_2$ escapes 4 times faster than $O_2$. If $1/2$ of the $H_2$ escapes, the fraction of $O_2$ that escapes in the same time is $(1/2) / 4 = 1/8$.
