Question

what is the unit of a in vanderwall equation​

Answer 1

Answer:

a has units of . The factor - nb accounts for the volume occupied by the gas molecules. b has units of L/mol. Since b corresponds to the total volume per mole occupied by gas molecules, it closely corresponds to the volume per mole of the liquid state, whose molecules are closely layere

Answer 2

Answer:

In a similar manner, the term (V−nb) is the van der Waals equivalent of V in the ideal gas equation. So to keep the unit as for volume in the second term, the unit for b must be Lmol−1
