Question

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 contains $n_1=5$ and $n_2=4$ moles of ideal gas at pressures $p_1=1 \mathrm{~atm}$ and $p_2=2 \mathrm{~atm}$, respectively. When the partition is removed, the mixture attains and equilibrium pressure of

Professor PC Thomas Classes · Answer

(d) : As, pressure at equilibrium is given by, \ $ \begin{aligned} & P_{e q}=\frac{P_1 V_1+P_2 V_2}{V_1+V_2} \ & P_{e q}=\frac{1 	imes 2+2 	imes 3}{2+3} \ & P_{e q}=\frac{8}{5}=1.6 \mathrm{~atm} \end{aligned} $
