Chapter , Problem 12E

(choose chapter or problem)

The graph below shows the change in pressure as the temperature increases for a

\(1-\text { mol }\) sample of a gas confined to a \(1-L\) container. The four plots correspond to an ideal gas and three real gases: \(\mathrm{CO}_{2}, N_{2}, \text { and } \mathrm{Cl}_{2}\).

(a) At room temperature, all three real gases have a pressure less than the ideal gas. Which van der Waals constant, \(a \text { or } b \text\), accounts for the influence intermolecular forces have in lowering the pressure of a real gas?

(b) Use the van der Waals constants in Table  to match the labels in the plot

\((A, B, \text { and } C)\) with the respective gases

\(\left(\mathrm{CO}_{2}, \mathrm{~N}_{2}, \text { and } \mathrm{Cl}_{2}\right)\).[Section 10.9
