P4-6 AOrthonitroanaline(animportantintermediateindyes-calledfastorange)isformedfromthereaction of orthonitrochlorobenzene (ONCB) and aqueous ammonia (see explosion in Figure E13-2.1 in Example 13-2). Stoichiometry Chapter 4 The liquid-phase reaction is first order in both ONCB and ammonia with k=0.0017m3/kmol. min at 188C with E=11,273cal/mol. The initial entering concentrations of ONCB and ammonia are 1.8kmol/m3 and 6.6kmol/m3, respectively (more on this reaction in Chapter 13). (a) Set up a stoichiometric table for this reaction for a flow system. (b) Write the rate law for the rate of disappearance of ONCB in terms of concentration. (c) Explain how parts (a) and (b) would be different for a batch system. (d) Write rA solely as a function of conversion. (e) What is the initial rate of reaction (X=0) at 188C ? rA= at 25C?rA= at 288C ? rA= (f) What is the rate of reaction when X=0.90 at 188C ? rA= at 25C ? rA= at 288C ? rA= (g) What would be the corresponding CSTR reactor volume at 25C to achieve 90% conversion and at 288C for a feed rate of 2dm3/min at 25C ? V= at 288C ? V=
