take place in a 10-dm3 CSTR. What are the effluent concentrations for a volumetric feed rate of 1000 dm3/min at a concentration of A of 0.3 mol/dm3?

The inlet temperature is 283 K.

Additional information

CPA = CPB = CPC = 200 J/mol · K

k1 = 3.3 min–1 at 300 K, with E1 = 9900 cal/mol

k2 = 4.58 min–1 at 500 K, with E2 = 27,000 cal/mol

ΔHRx1A = –55,000 J/mol A

UA = 40,000 J/min · K with Ta = 57°C

ΔHRx2B = –71,500 J/mol B
