The liquid-phase irreversible reaction A → B + C is carried out in a CSTR. To learn the rate law, the volumetric flow rate, υ₀, (hence τ = V/υ₀) is varied and the effluent concentrations of species A are recorded as a function of the space time τ. Pure A enters the reactor at a concentration of 2 mol/dm³. Steady-state conditions exist when the measurements are recorded.

Determine the reaction order and specific reaction-rate constant.
