A vessel has two equal compartments

A

and

B

containing

{\mathrm{H}_2}

and

{\mathrm{O}_2}

respectively, each at 1 atm pressure. If the wall separating the compartment is removed, the pressure:

View answer and explanation

Correct option: A

Will remain unchanged in

A

and

B

Option A (Will remain unchanged in

A

and

B

) is correct because after removing the wall, each gas expands to fill the entire volume, but the partial pressure of each gas remains the same.
