Unformatted text preview: Since collisions of real gases are non-elastic, the term n 2 a/V 2 is correcting for the interactions of these particles. The value of a is a constant, and must be experimentally determined for each gas. Since real gas particles have real volume, the nb term is correcting for the excluded volume. The value of b is constant, and must be experimentally determined for each gas. These constants can be found in CRC Handbook of Chemistry and Physics in a table. Ideal gases are simpler and use the Ideal gas law at low to moderate pressures and temperatures that arent too low. Real gases deviate from the ideal gas law at high temperatures and low temperatures, and the Van der Waals equation can be used to account for the volume and pressure change....
