An industrial chemist determines that the rate of change of a reactant's concentration CCC (in mol/L) with respect to the dosage of a catalyst xxx (in ml) is given by the model:
dCdx=(4x−5)(3x+2)(4x+5)\frac{dC}{dx} = (4x - 5)(3x + 2)(4x + 5)dxdC=(4x−5)(3x+2)(4x+5)
Find the general expression for C C\,C in terms of xxx, writing your answer in its simplest form.
