What does a small value for the van der Waals constant a suggest about the molecules of the gas?
A small value for the van der Waals constant for a molecules of the gas suggests that the real gas deviates negligibly from ideal gas. In other word, the real gas becomes to be ideal when the van der Waal's constant approaches zero.

Enter your answer in the provided box. Because the van der Waals constant b is the excluded volume per mole of a gas, we can use the value of b to estimate the radius of a molecule or an atom. Consider a gas that consists of molecules, for which the van der Waals constant b is 0.0295 L/mol. Estimate the molecular radius in picometers. Assume that the molecules are spherical.
The van der Waals equation of state was designed (by Dutch physicist Johannes van der Waals) to predict the relationship between press temperature T for gases better than the Ideal Gas Law does: b) - RT The van der Waals equation of state. R stands for the gas constant and n for moles of gas The parameters a and b must be determined for each gas from experimental data. Use the van der Waals equation to answer the questions in...
