Two ideal gases in a box are initially separated by a partition. Let N1, V1 and N2, V2 be the numbers of particles and volumes occupied by the two systems. When the partition is removed, the pressure of the mixture at an equilibrium temperature T, is
1
\(\rm k_B T\left(\frac{N_1+N_2}{2\left(V_1+V_2\right)}\right)\)
2
\(\rm k_B T\left(\frac{N_1+N_2}{V_1+V_2}\right)\)
3
\(\rm k_B T\left(\frac{N_1}{V_1}+\frac{N_2}{V_2}\right)\)
4
\(\rm\frac{1}{2} k_B T\left(\frac{N_1}{V_1}+\frac{N_2}{V_2}\right) \)
