A rigid 9.8 L container is charged by means of 1.4 mol of helium gas at 8 C. Explain an identical container is charged with 1.4 mol of carbon dioxide gas at the same temperature. Utilize the van der Waals equation of state with the data below to predict the difference in pressure between the two containers.
Gas a (m6Pa/mol2) b (m3/mol)
He 3.457E-3 2.37E-5
CO2 0.3640 4.267E-5
