Ere ative atomic mass of hydrogen 1.0, carbon 12.0 and oxygen 16.0 the idre gas constant 8.31 jk'mol1 and 0°c-273 k section a 1 elementary gaseous reaction a+br is carried out in a mixed flow reactor (mfr) to produce product r. reaction kinetics -fa kcacb [mol/(l-min)l. two separate streams containing the reactants a and b respectively: stream 1: volume flow rate u1 - 100 u/min; this stream contains 100 mmol/l reactant a and 400 mmol/l non-reactive inert gas stream 2: volume flow rate u2 = 20 l/min, this stream contains 500 mmol/l pure reactant b (a) under the isothermal reaction condition of t = 500°c and ambient pressure, the rate constant k = 0.291 l/(mmol-min) for xa-90% conversion of reactant [13 marks] a, what size of the mfr is needed? (b) the temperatures of the two input streams are still t 500°c at ambiert 17 marks] pressure. if an adiabatic mfr is used, what is the size of the reactor for xa 90%? data: assume the equivalent specific heat capacity of the gases' mixture system is constant throughout the reaction: enthalpy of the reaction: activation energy of the reaction: e 30 kj/mol сре 0.3 kj/(k-mol) ahr -45 kj/mol
