Homework Statement
For a gas obeying Dieterici's equation of state:
P(V-b) = RTexp(-a/RTV)
for one mole, prove that the equation of the inversion curve is
P = ((2a/b^2) - (RT/b)) * exp((1/2) - (a/(RTb)))
and hence find the maximum inversion temperature.

The Attempt at a Solution
So, I know that for the inversion curve, the condition is (dV/dT) = V/T (where the derivative is evaluated at constant pressure). But this would need implicit differentiation to find dV/dt ... and it seems completely intractable - is there something I'm missing?
