4.73 One kilogram of air, initially at 5 bar, 350 K, and 3 kgof carbon dioxide (CO2), initially at 2 bar, 450 K, are con-fined to opposite sides of a rigid, well-insulated container, asillustrated in Fig. P4.73. The partition is free to move and al-lows conduction from one gas to the other without energystorage in the partition itself. The air and carbon dioxide eachbehave as ideal gases. Determine the final equilibrium tem-perature, in K, and the final pressure, in bar, assuming con-stant specific heats.
