Real vs Ideal Gases
Answer the following question using the table of van der Waals parameters below.
Which of the above gases takes up more of the ideal volume inside a flask
At a temperature of 320 K and a pressure of 16 atm, the molar volume of ammonia (NH3) is about 10% less than that of an ideal gas under those conditions. The best explanation for this observation is?
The graph at the right shows PV/RT as a function of pressure for one mole of an ideal gas (horizontal dashed line) and for several real gases. One notices that for most of the real gases PV/RT is smaller than predicted by the ideal gas law for lower pressures. The reason for this deviation from ideal behavior is:

At very high pressures, gas properties deviate from those predicted by the ideal gas law. The actual volume of the gas will be…
