Which of the following of a protein molecule determines the strength of van der Waals force?

Correct Answer: The surface area of the molecule
The surface area of a molecule determines the strength of the van der Waals interactions between molecules. The larger the surface area, the larger the attractive force between two molecules, and the stronger the intermolecular forces. They are weak interactions caused by momentary changes in electron density in a molecule.

What is the power of diminishment of van der Waals force with respect to distance?

Real gases conform more closely with the van der Waals equation of state than the ideal gas equation of state.

The value of compressibility factor at the critical state for a van der Waals gas is

A van der Waals bond is a _________ bond.

For the Van der Waals real gas equation Statement I: The unit of constant a is atm.L2/mole2 Statement II: The unit of constant b is L

Van der Waals forces are the only attractive forces present in nonpolar compounds.

In physical adsorption the enzymes are attached to the matrix through hydrogen bonding, van der Waals forces, or hydrophobic interactions; whereas in ionic bonding, the enzymes are bound through?

What are the units of “b” in van der Waals equation?

The solid phase of an element follows van der Waals bonding with inter-atomic potential $$V\left( r \right) = - \frac{P}{{{r^6}}} + \frac{Q}{{{r^{12}}}}$$    where, P and Q are constants. The bond length can be expressed as

The internal pressure of a van der Waals gas is
