Multiple choice

A vessel has two equal compartments $A$ and $B$ containing $H_2$ and $O_2$ respectively, each at $1\space atm$ pressure. If the wall separating the compartment is removed, the pressure :

  1. Will remain unchanged in $A$ and $B$
  2. Will increase in $A$ and decrease in $B$
  3. Will decrease in $A$ and increase in $B$
  4. Will increase in both $A$ and $B$

A Correct answer
Explanation

According to Dalton's Law or simply the nature of ideal gases, if the compartments are equal and the pressure is the same, removing the wall does not change the pressure because the total volume and total moles remain constant relative to the initial state.
