Question
Q1. The following is an irreversible liquid-phase reaction which follows elementary rate law. A +B →C+ 2D The reaction is carried out isothermally in a continuous flow system at 50 °C and 1 atm. A stream of 30 mol/h A is fed into the reactor at 5 m³/h. Another stream of 60 mol/h B is fed into the reactor at 5 m³/h too. The specific reaction constant is 0.22 m³/(h.mol) and the activation energy is 8.2 kcal/mol. Write four equations to relate concentration of species A, B, C and D with initial concentration of the limiting reactant and conversion only. (а) (b) Determine the conversion of the reaction if the volume of a PFR reactor is 15m³. (c) Determine the rate of reaction for (b). Prove that the reaction rate of the above process increases about 4 times when the reaction takes place at 90 °C to achieve the same conversion.
