Question

A liquid phase reaction A+B-->C is conducted in a 50-L batch reactor. The reaction is first-order with respect to each reactant.

a) determine the time required for 90% conversion of A, if:
i) the reaction occurs adiabatically
ii) the reaction occurs isothermally at To

b) determine Q and Tc (as a function of time), if a cooling coil is placed in the tank to maintain the isothermal conditions in (a) part(ii)

c)

For (a) part (i), sketch the conversion-versus-time and temperature-versus-time profiles. Given: CA0 = 0.5 M and CB0 = 0.75 M. The initial temperature (T0) is 400 K, and the heat capacity of the reactor contents is 3.8 J/g/K. The fluid density is 0.75 g/cm3 , and the heat transfer parameter U*Ac for part (b) is 100 W/K. The reaction is exothermic (-145 KJ/mol) and kA = 1.4*107 *exp(-7700/T) (L/mol/min).
