Solution

The correct option is A $P$
A box of $1 L$ capacity is divided into two equal compartments by a thin partition which are filled with $2 g$ $H_{2}$ and $16 g$ $C H_{4}$ respectively.

The pressure in each compartment is recorded as $P a t m$ . The total pressure when the partition is removed will be $P$

In both the compartments, the volume, temperature, number of moles and pressure are the same. When the partition is removed, the number of moles and the volume are doubled at a constant temperature, the pressure remains constant. $P V = n R T$

So, the correct option is $A$
