The method I would use would be to arrange the system in it's
initial state (all the O2 on one side of the box, all the N2 on
the other) then use the Metropolis equations to cycle through the
configurations until minimum energy/maximum entropy was achieved
(equilibrium) at some fixed temperature.

See:

  Teller E. 'Equations of State Calculations by Fast Computing Machines',
