Crash Course Chemistry: Episode #14 – Real Gases

1. Describe the van Der Waals Equation. (ID all variables)
2. Solve the following problem using the van Der Waals Equation:
If 1.00 mol of an ideal gas were confined to 22.4 L at 0.0 °C, it would exert a pressure of 1.00
atm. Use van der Waals equation and the constants below, to estimate the pressure exerted
by 1.00 mol of Cl2(g) in 22.41 L at 0.0 °C.
R = 0.08206 L-atm/mol-K,
a = 6.49 L2-atms/mol2 and
b = 0.0563 L/mol
