A : The value of van der Waal's constant 'a' of Cl_(2) is larger than that of F_(2) R : Larger the surface area, higher will. Be intermolecualr forces of attraction .

The van der Waal's gas constant, a is given by

In the van der Waals equation

For three different gases, value of van der waals' constant 'a' and 'b' are given. What is the correct orde of liquefaction of gases?

The values of the van der Waals constants for a gas a = 4.10 dm^(6) "bar" mol^(-2) and b = 0.035 dm^(3) mol^(-1) . Calculate the values of the critical temperature and critical pressure for the gas.
