pi is corrected for the finite volume of the particles. The attractive forces have not yet been taken into account. The attractive forces among molecules will be discussed in Chapter 10. Wall (a) Wall (b) Figure 5.27 (a) Gas at low concentration-relatively few interactions between particles. The indicated gas particle exerts a pressure on the wall close to that predicted for an ideal gas. (b) Gas at high concentration-many more interactions between particles. The indicated gas particle exerts a much lower pressure on the wall than would be expected in the absence of interactions. 5.8 Real Gases 215 modify the assumptions of the kinetic molecular theory to fit the behavior of real gases? The first person to do important work in this area was Johannes van der Waals (1837-1923), a physics professor at the University of Amsterdam who in 1910 received a Nobel Prize for his work. To follow his analysis, we start with the ideal gas law, nRT p=-V Remember that this equation describes the behavior
