Question

the ideal gas law is represented by pv = nrt. the van der waals equation introduces correction terms to account for real gas behavior. which term in the van der waals equation corrects for the volume of gas molecules? nrt p -nb v in the van der waals equation, (p + a(n/v)^2), the term a(n/v)^2 corrects for: the temperature of the gas. the kinetic energy of the gas molecules. the volume occupied by the gas molecules. the intermolecular attractive forces between gas molecules.

Explanation:

The van der Waals equation is $(P+\frac{an^{2}}{V^{2}})(V - nb)=nRT$. The term $-nb$ corrects for the volume of gas molecules as it accounts for the finite - size of gas molecules. The term $a(\frac{n}{V})^{2}$ corrects for the intermolecular attractive forces between gas molecules. In the first question, we are looking for the volume - correction term and in the second for the intermolecular - force correction term.

Answer:

1. C. -nb
2. D. The intermolecular attractive forces between gas molecules.
