Problem 1PE

Using the van der Waals Equation

If 10.00 mol of an ideal gas were confined to 22.41 L a: 0.0 aC. it would exert a pressure of

10.00        atm. Use the van der Waals equation and Table to estimate the pressure exerted by

1.000        mol of Ct2{g) in 22.41 L at 0.0 aC.

Calculate the pressure of a 2.975-mol sample of N2 in a 0.7500-L flask at 300.0 aC using the van der Waals equation and then repeat the calculation using the ideal-gas equation. Within the limits of the significant figures justified by these parameters, wl the xleal-gas equation overestimate or underestimate the pressure, and if so by how much?

(a) Underestimate by 17.92 atm. (b) Overestimate by 21.87 atm. (c) Underestimate by 0.06 atm. (d) Overestimate by 0.06 atm.
