What is excluded volume or co volume How is it related to the actual volume of the gas molecules?

It is also known as the excluded volume or co-volume. The numerical value of ‘b’ is found to be four times the actual volume occupied by the gas molecules. Here, P represents the pressure of the gas in atmospheres, V represents the volume of the gas in litres and n represents the number of moles of the gas.

What is excluded volume or volume of the gas?

The simplistic answer would be that the actual volume of a gas is the volume a given gas will occupy in a container at a given pressure, while the excluded volume is the space between the atoms which cannot be occupied by an atom of the gas due to the size of the atoms in question.

Why is the volume of a gas the same as the volume of its container?

Because gases expand to fill their containers, it is safe to assume that the volume of a gas is equal to the volume of its container. The difference between the volume of a gas and the volume of the liquid or solid from which it forms can be illustrated with the following examples.

What is actual volume of a gas?

The volume occupied by the gas molecules which their movement is restriced in that area is called excluded volume. Actual volume (or effective volume) = Vcontainer – Voccupied by gas molecules.

What is meant by excluded volume?

In liquid state theory, the ‘excluded volume’ of a molecule is the volume that is inaccessible to other molecules in the system as a result of the presence of the first molecule.

What do you understand by the excluded volume so that excluded volume is four times of actual volume of the gas?

The excluded volume b is not just equal to the volume occupied by the solid, finite-sized particles, but actually four times that volume. To see this, we must realize that a particle is surrounded by a sphere of radius 2r (two times the original radius) that is forbidden for the centers of the other particles.

What is excluded volume show that excluded volume is four times the actual volume of gas?

We have to find that the excluded volume is 4 times the volume of one mole of a gas or not. For this excluded volume correction will be done in the ideal gas equation, P=RTV. 8V2 = 4V, so, the excluded volume is 4 times the original volume.

What do you understand by excluded volume so that excluded volume is four times of actual volume of the gas?

Do gases have the same volume as the container in which they are contained?

Each gas in a mixture of gases stored in the same container has the volume of that container.

How does the volume of an entity of an ideal gas compare to the volume of its container?

(There is no loss of kinetic energy.) The volume of an ideal gas entity is insignificant (zero) compared to the volume of the container. Assuming this, we can put all our observations and gas laws together into a single equation known as the ideal gas law.

What do understand by excluded volume?

In polymer science, excluded volume refers to the idea that one part of a long chain molecule can not occupy space that is already occupied by another part of the same molecule.

What is excluded volume effect?

The excluded volume effect favors any chemical reaction in which the volume decreases. This includes ligand binding by a protein and the association of protein subunits to form oligomers. The equilibrium constant for such a reaction is increased with the increasing concentration of macromolecules in the solution.
