A) The parameter a accounts for the finite size of the molecule, not included temperature in the ideal gas law
B) The parameter a accounts for the shape of gas phase molecules
C) The parameter a accounts for intermolecular interactions present in the molecule
D) The parameter a has no physical significance and van der Waals introduced it as a numerical correction factor only
E) The parameter is a correction factor to the volume of the container
Correct Answer: C
Solution :
In van der Waals equation \[\left[ P+\frac{{{n}^{2}}a}{{{V}^{2}}} \right](V-nb)=nRT\] Where, P = pressure, V = volume T = temperature, n = moles of the gas and parameter d accounts for intermolecular inter-actions present in the molecule.You need to login to perform this action.
