Question

0.5 mole of each of $H_{2}$, $SO_{2}$ and $CH_{4}$ are kept in a container. A hole was made in the container. After 3 h, the order of partial pressures in the container will be

• A. $pSO_{2}>pH_{2}>pCH_{4}$
• B. $pSO_{2}>pCH_{4}>pH_{2}$
• C. $pH_{2}>pSO_{2}>pCH_{4}$
• D. $pH_{2}>pCH_{4}>pSO_{2}$

Hint:

Heavier gases diffuse slower and remain in the container longer.

Answer 1

The Correct Option is B
