Question 81

An industrial chemist determines that the rate of change of a reactant's concentration $C$ (in mol/L) with respect to the dosage of a catalyst $x$ (in ml) is given by the model:

\frac{dC}{dx} = (4x - 5)(3x + 2)(4x + 5)

Find the general expression for $C\,$ in terms of $x$ , writing your answer in its simplest form.
