For carbon dioxide gas the constants in the van der waals, Ask an Expert

Academics

For carbon dioxide gas the constants in the van der Waals equation are a = 0.364 J m3/mol2 and b = 4.27 x 10-5 m3/mol.

a. If 1.00 mol of CO2 gas at 350 K is confined to a volume of 400 cm3, find the pressure of the gas using the ideal gas equation, and again using the van der Waals equation.

b. Which equation gives a lower pressure? Why? What is the percentage difference of the van der Waals equation result from the ideal-gas equation result?

c. On page 691 of your book the difference for CO2 between the ideal gas and van der Waal's equation is worked out to be 0.5%. Explain why your calculation is different than that in the book?
