1202 b) A 250 L CSTR and a 400 L CSTR are to be connected in series to handle a sec reaction with - a (mol/Lmin) and a reactant feed rate of 200 mol/min. The initial concentration of A is 2 mol/L. What will be the conversion achieved when (1) smaller CSTR is followed by the larger CSTR and (ii) larger CSTR is followed by the smaller CSTR 2a) In a CVBR, the following half-life data are obtained for the reaction A + 2B + C + D, when the reaction is carried out at different initial concentrations of A and B. Determine the kinetics of the reaction. 6 1.0 2 molt 1 14 1.6 1 14 26 16 11. 19.1 b) The first order irreversible gas-phase reaction AB + C is carried out in a WVBR with pure A initially present. The specific reaction rate constant = 0.4 ! (i) After how much time will the reactor volume be 30% more than the initial volume? (ii) What is the conversion at this time? 3a)' The solid catalyzed gas phase reaction A + 2B is to be carried out in a fixed bed reactor. Pure A is charged into the reactor at 150 °C and a pressure of 5 atm at a rate of 50 kmol/hr. The rate equation is found to be: . kmol 25p, (am) Tor kycatalys' 1+225/7 Find the weight of the catalyst required for obtaining 80% conversion of A. b) The elementary series reactions A R S with ki = k2 are carried out in a continuous stirred tank reactor. Find expressions for the maximum concentration of R and the corresponding space time. 4 .) Ethanol car be produced by the following vapor phase reaction from ethylene CHa + H2O C2H5OH. The value of AGº for the above reaction at 1 atm and 125° is 5040 J. Calculate the maximum conversion obtained if an isothermal reactor operating at 125°C and 2 atm is fed with a mixture of 50 mole% steam. Assume that the gases behave ideally. At a space time of 300 s, a CSTR is operated which maximizes the concentration of R for the elementary reactions: A - RS, ki = 0.0333/s, E1/E2 = 3. Find the value of k2. The feed to the reactor consists of pure A. Differentiate physical adsorption with chemisorption. PTO
