Question

what is vanderwall radius? Explain with equations...​

Answer 1

Answer:

In chemistry, a van der Waals radius is a measure for the size of an atom that is not chemically (ionically or covalently) bound. In general a van der Waals radius is defined as half the closest distance of two equal, non-covalently bound, atoms. ... Hence, a van der Waals radius r0 may be estimated from b/NA = 4π/3 r03.

Answer 2

Answer:

It is called the Van der Waals equation. For one mole of a gas, it can be written as. \[\left( {p + \frac{a}{{{V^2}}}} \right)\left( {V – b} \right) = RT.\] This equation takes into account the attractive and repulsive forces between molecules.
