A container has two chambers of volumes $V_1 = 2$ litres and $V_2 = 3$ litres separated by a partition made of a thermal insulator. The chambers contain $n_1 = 5$ and $n_2 = 4$ moles of ideal gas at pressures $p_1 = 1$ atm and $p_2 = 2$ atm, respectively. When the partition is removed, the mixture attains an equilibrium pressure of

Show answer and solution

Sol.

P_1V_1 + P_2V_2 = P(V_1 + V_2)

1(2) + 2(3) = P(2 + 3)

\frac{8}{5} = P

\Rightarrow 1.6

atm
