The liquid-phase irreversible reaction A+B+C is carried out in a CSTR. To learn the rate law, the volumetric flow rate, UO, (hence t = V/) is varied and the effluent concentrations of species A are recorded as a function of the space-time t. Pure A enters the reactor at a concentration of 2 mol/dm3. Steady-state conditions exist when the measurements are recorded.
