2. The zero-order exothermic liquid-phase reaction, AB, is carried out at 85C in a jacketed 0.2m3 CSTR. The coolant temperature in the reactor is 32F. The heat-transfer coefficient is 120W/m2K. Determine the critical value of the heat-transfer area below which the reactor will run away and explode. Additional Information: k=1.127kmol/m3minat40Ck=1.421kmol/m3minat50C The heat capacity of the solution is 4J/C/g. The solution density is 0.90kg/dm3. The heat of reaction is 500J/g. The feed temperature is 40C and the feed rate is 90kg/min. MW of A=90 g/mol
