A physical chemistry student derives an expression for the rate of effusion through a small orifice: dndt=PA2πmkT⋅(1+aV)\frac{dn}{dt} = \frac{PA}{\sqrt{2\pi mkT}} \cdot \left(1 + \frac{a}{V}\right), where PP is pressure, AA is orifice area, mm is molecular mass, and aa is a van der Waals parameter. To check this result, which limiting case provides the clearest assessment of physical reasonableness?
