For the non-zero volume of the molecules...

For the non-zero volume of the molecules, real gas equation for `n` mol of the gas will be

A

`(P+(a)/(V^(2)))V=RT`

B

`PV=nRT+nbP`

C

`P(V-nb)=nRT`

D

Both (`b`) and (`c`) are true.

Text Solution

Verified by Experts

For `n mol` of a real gas
`(P+(n^(2)a)/(V^(2)))(V-nb)=nRT`
When volume of molecules can't be neglected,
`P(V-nb)=nRT`
`PV=nRT+nbP`

For the non-zero value of the force of attraction between gas molecules, gas equation will be

Real gases do not obey ideal gas equation,

At absolute zero, the molecules of a gas come at perfect rest.

Comment on the statements : (i) Molecular volume in a gas can be neglected as compared to the total volume of the gas. (ii) Forces of attraction and repulsion among the gas molecules are negligible.

The main reason for deviation of gases from ideal behaviour is few assumptions of kinetic theory . These are (i) there is no force of attraction between the molecules of a gas (ii) volume of the molecules of a gas is negligibly small in comparison to the volume of the gas (iii) particles of a gas are always in constant random motion .

Which of the following represents the van der Walls equation for n moles of a real gas ?

van der Waal's equation for calculating the pressure of a non ideal gas is (P+(an^(2))/(V^(2)))(V-nb)=nRT van der Waal's suggested that the pressure exerted by an ideal gas , P_("ideal") , is related to the experiventally measured pressure, P_("ideal") by the equation P_("ideal")=underset("observed pressure")(underset(uarr)(P_("real")))+underset("currection term")(underset(uarr)((an^(2))/(V^(2)))) Constant 'a' is measure of intermolecular interaction between gaseous molecules that gives rise to nonideal behavior. It depends upon how frequently any two molecules approach each other closely. Another correction concerns the volume occupied by the gas molecules. In the ideal gas equation, V represents the volume of the container. However, each molecule does occupy a finite, although small, intrinsic volume, so the effective volume of the gas vecomes (V-nb), where n is the number of moles of the gas and b is a constant. The term nb represents the volume occupied by gas particles present in n moles of the gas . Having taken into account the corrections for pressure and volume, we can rewrite the ideal gas equation as follows : underset("corrected pressure")((P+(an^(2))/(V^(2))))underset("corrected volume")((V-nb))=nRT AT relatively high pressures, the van der Waals' equation of state reduces to

Is the excluded volume of a real gas equal to the actual E volume of the molecules of a gas ?

Does co-volume represent the actual volume of the molecules in a gas ?

Vander Waals' equation of state is obeyed by real gases. For n moles of a real gas, the expression will be
