what is wander wall force
Answers
Answer:
Van der Waals forces' is a general term used to define the attraction of intermolecular forces between molecules. There are two kinds of Van der Waals forces: weak London Dispersion Forces and stronger dipole-dipole forces.
Explanation:
Answer:
Van der Waals equation is required for special cases, such as non-ideal (real) gases, which is used to calculate an actual value. The equation consist of:
(P+n2aV2)(V−nb)=nRT(1)
(1)(P+n2aV2)(V−nb)=nRT
The V in the formula refers to the volume of gas, in moles n. The intermolecular forces of attraction is incorporated into the equation with the n2aV2n2aV2 term where a is a specific value of a particular gas. P represents the pressure measured, which is expected to be lower than in usual cases. The variable b expresses the eliminated volume per mole, which accounts for the volume of gas molecules and is also a value of a particular gas. R is a known constant, 0.08206 L atm mol-1 K-1, and T stands for temperature.
Unlike most equations used for the calculation of real, or ideal, gases, van der Waals equation takes into account, and corrects for, the volume of participating molecules and the intermolecular forces of attraction
