Can a Bertholet Gas Show a Critical Point?

Obtain an expression for the partial derivative of P with respect to V, at constant T, for a Bertholet Gas, page 49, Equation 2-30, Dykstra's "Physical Chemistry, a Modern Introduction", in the spirit of the derivation for the critical constants of a van der Waals' gas, page 117, and answer the question of whether or not a Bertholet Gas can show an inflection point in the P-V isotherm. In your (formula) answer, use `a' , `b', `R', `T', and `V' in your answer.
You can use two asterisks, `**', or a caret, `^', to indicate powers, i.e., v^2 and v**2 both mean v squared.

Answer is:
a Bertholet Gas can have a critical point
YesNo

Query, is the above formula (and Yes/No answer) correct?
