Question

A first order, liquid-phase reaction A ?products, is conducted in a 2000 L CSTR. The feed contains pure A, at a rate of 300 L min-1 , with an inlet concentration of 4.0 mol L-1 . The following additional data are available:

cP = 3.5 J g-1 K-1;

? = 1.15 g cm-3 ;

?HRA = -50 kJ mol-1

(you can assume that these values are constants)

kA = A e-EA/RT = 2.4 x 1015e-12,000/T min-1 , with T in K

Determine the conversion and operating temperature, T, at steady-state based upon adiabatic operation if : (a) T0 = 290 K, (b) 298 K, (c) 305 K. Describe if steady states are stable or unstable.
