Calculate molecular diameter of He if b (van der Waals’ constant for volume) for He is 24. mL `mol^(-1)`.

The unit of van der Waals constant 'a' is

Write the units of van der waals constants 'a' and 'b'.

The inversion temperature Ti(K) of hydrogen is (Given van der Waal’s constant a and b are 0.244 atm L^2 mol^(-2) and 0.027 L mol^(-1) respectively.)

Which of the following is the unit of van der waals gas constant b-

What property of molecules of real gases is indicated by van der Waal’s constant ‘a’?

The van der Waals' constants of a gas are a=0.687dm^2mol^(-2)b=0.0226dm^3mol^(-1)

The van der Waals Constants 'a' for different gases have been given as

(i) Any real gas behaves ideally at very low pressure and high temperature explain. (ii) The value of van der waals constant 'a' for N_(2) and NH_(3) are 1.37 and 4.30 L^(2)*atm*mol^(-2) respectively explain the difference in values.

This question has Statement I and Statement II. Of the four choices given after the Statements, choose the one that best describes the two Statements. Statement -I: The gas with greater value of 'a'can be easily liquefied. Statement - II : The van der Waals constant ‘a’ measures the intermolecular force among gas molecules.
