The formation of nitroanaline (an important intermediate in dyes) is formed from the reaction of orthonitrochlorobenzene (ONCB) and aqueous ammonia with ammonium chloride as a by-product. NO, NO, NH, + 2NH, + NH,CL ONCB Nitroanaline Let the reaction be represented symbolically as A + 2B →C +D The reaction occurs in the liquid phase and is first order in both ONCB and ammonia with k = 0.0017 m /kmol.min at 461K with E = 11273 cal/mol. The initial entering concentrations of A (ONCB) and B (ammonia) are 1.8 kmol/m³ and 6.6 kmol/m², respectively. a. Set up a stoichiometric table for this reaction for a flow system b. Write the rate law for the disappearance of ONCB, -rA solely as a function of conversion X c. What is the rate of reaction, -r, when X = 0.9 at i. 461 K ii. 561 K d. What would be the CSTR reactor volume to achieve 90% conversion at 561 K for a molar feed rate of 2 mol/min. Calculate the space time for this reactor. (Use R=1.987 cal/mol. K, where R is the universal gas constant)
