Question 4 Reactant A decomposes by three simultaneous reactions to form three products in three gas-phase reactions shown below. AX Reaction 1 A B Reaction 2 A Y Reaction 3 The reaction was conducted at 300 K. The initial concentration of species A is 0.4 M and the volumetric flowrate is 2 dm's. B is the desired product. The reaction rate constants are shown in Table Q4. Table Q4: Reaction rate Reaction Rate law Rate constants 1 -PIA-FX k1k1-0.0001 mol/dm's 2 A:-0.0015¹ -F2A-ra-k₂CA --r-kiCA² ks-0.008 dm³/mol.s 3 The selectivity reached the maximum at a concentration of CA" where a. Determine the maximum selectivity that can be achieved. If the reaction is carried out in a CSTR, determine the volume required. Determine the maximum conversion of species A. Determine the effluent concentration of B, X and Y (unit:mol/dm³). Determine the yield to form B at maximum selectivity. ---END OF QUESTION PAPER--- 7 b. C. d. c.
