PPT Slide
- Real gas molecules actually have finite molecular volumes, fixed by the sizes of their atoms and the lengths of their bonds.
- The properties of real molecules require an adjustment of the kinetic-molecular model.
- At low temperatures and high pressures, changes in the model are necessary in order to predict gas behavior quantitatively.
- For one mole of real gas, PV/RT can be >1 or <1.
Concept 5-12. Why intermolecular attractions and molecular volume cause gases to deviate from ideal behavior at low temperature and high pressure
