1. For the two CSTRs in series, 40% conversion is achieved in the first reactor. Using the data below; What is the volume of each of the two reactors necessary to achieve 80% overall conversion of the entering species A?

Rate constants for the reaction NO2+CO NO+CO2 are 1.3 1/M*s at 700K and 23.0 1/M*s at 800K. 1) What is the value of the activation energy in kJ/mol? 2) What's the rate constant at 730K? 3. The irreversible reaction as shown below (3 marks) (3 marks) A+B+C is to be carried out in a flow reactor at liquid phase. Given that there are two reactors available, an 800 dm PFR that can only be operated at 300 K and a 200 dm CSTR that can be operated at 350 K. The two feed streams to the reactor mix to form a single feed stream that is equal molar in A and B, with a total volumetric flow rate of 10 dm /min. Which of the two reactors will give the highest conversion ( 10 marks) Given : at 300 K, k = 0.07 dm /mol-min E = 85000 J/mol-K CAO = CBo = 2 mol/dm3 VAO = VBO = 0.5* Vo = 5 dm/min
