Units of a and b in van der Waal's equation `(P+(an^(2))/(V^(2)))(V-nb)=nRT` are

A

`L^(2)atm^(-1), L`

B

`atm L^(-2), L^(-1)`

C

`L^(2) atm^(-1) mol^(-2), L mol^(-1)`

D

`atm L^(2)mol^(-2), L mol^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
D
Units of `(ax^(2))/(V^(2)) = atm`
Units of `a = (atmxxL^(2))/(mol^(2)) = atmL^(2)mol^(-2)`
Units of n b = L
Units of `b = (L)/(mol) = L mol^(-1)`

Van Der Waals Equation

In the van der Waals equation

For real gases, the relation between P, V and T is given by an van der Waals equation, (P+(an^(2))/(V^(2)))(V-nb)=nRT . For the following gases CH_(4),CO_(2), O_(2),H_(2) which gas will have (i) highest value of 'a' and (ii) lowest value of 'b' respectively?

Find out the unit and dimensions of the constants a and b in the van der Waal's equation ( P + (a)/(V^(2))) ( V - b ) = R t , where P is pressure , v is volume , R is gas constant , and T is temperature.

For real gases the relation between p, V and T is given by c=van der Waal's equation (p+ (an^(2))/V^(2)) (V-nb)=nRT where, 'a' and 'b' are van der Waal's constanrs, 'nb' is approximately equal to the total volume of the molecules of a gas. 'a' is the measure of magnitude of intermolecular attraction. (i) Arrange the following gases in the increasin order of 'b'. give reason. O_(2), CO_(2), H_(2), He (ii) Arrange the following gases in the decreasing order of magnitude of 'a'. Give reason. CH_(4), O_(2), H_(2)

The van der Waal equation of gas is (P + (n^(2)a)/(V^(2))) (V - nb) = nRT

Deviation of real gases from ideal behaviour can be studied by plots of compressibility factor (Z) vs p. The copressibility factor is Z=(pV)/(nRT) The compressibility factor for 1 mole of a gas obeying van der Waals gas equation at 0^(@)C and 100 atm pressure is found to be 0.5. The van der Waals gas equation is (p(an^(2))/(V^(2)))(V-nb)=nRT What is the significance of van der Waals constant 'a'?
