Van der Waal’s constant “a” is a measure of
Magnitude of repulsive forces between molecules
Magnitude of attractive forces between molecules
Excluded volume of a molecule
None of the above
Greater the value of “a” greater the attractive forces between molecules and hence greater the ease of liquefaction.
The value of critical temperature TC for a gas is :
In Van der Waals equation of state of the gas law, the constant b is a measure of__.
