Van der waals equation relates the pressure p and the

Question

Question: Van der Waal's equation relates the pressure, P, and the volume, V , of a fixed quantity of a gas at constant temperature T . For a, b, n, R constants, the equation is

(P + (n²a/V²))(V - nb) = nRT

(a) Express P as a function of T and V.

(b) Write a linear approximation for the change in pressure, ΔP = P - P0, resulting from a change in temperature ΔT = T - T0 and a change in pressure, ΔV = V - V0.
