Question

s to be carned out ih parallel tibes 3 m and 20 zmm inside diameter and long 20 mm inside diameter under constant pressure of 7 atm at 173 °C. The specific rate 0.015 s1 and the activation energy is 21 kJ/mol. How many tubes in parallel are needed to produce 125 kmol B per hour when the conversion of A is 75%. 17, Two stirred thanks at volüme V i and 2Vi are available for carrying out a first - order irreversible reaction at constant density and temperature. If the flow rate of the feed stream is v, wich of the following arrangements would give the highest production rate of product? (a) Parallel operation of the two reactors, with equal average residence times in each. (b) Parallel operation, with different average residence times. (c) Series operation, with the feed stream entering the larger reactor (d) Series operation with the feed stream entering the smaller reactor. molidm Using a color indicator which shows when the concentration of A fall Using a color indicator which shows when the concentration of A falls below 0.1 mol/dm 0 cm'or series of two CSTRs each havin The schemes (single CSTR having a volume of 40 volume of 400 cm3) are devised to explore the kinetics of the decomposition o f A. A feed

Explanation / Answer

reactor with the smallest volume should be the first one for highest production rate.So option d is correct.
