The dissolution (solubilization) of an oil contaminant into water is governed by the equation:

where k_l is a lumped mass transfer coefficient and C_s is the maximum solubility of the contaminant into the water (a constant). Given C(0)=2 mg/L, C_s = 500 mg/L and k_l = 0.1 day^-1, estimate C(0.5) and C(1.0) using Ralston's second order method for ordinary differential equations.
