For an exothermic reaction in the gas phase A-B (1st order) at an ideal stirred tank reactor (ATCR) write the heat and mass balances in the steady state and determine the number of steady states for the following data: CAO= 5.10 x 10-6 (mol/Lt); k= 6.98x1012 exp(-22300/1.987 T) (sec-1); V=1800 (cm3); Fo= 9.3 (cm3/sec). The supply temperature To= 300 K, and the cooling temperature Te=340 K. The value of (H ) = 15000 (cal/mol). The UA=1.28 (cal/sec-K) and Cp=0.80 (cal/cm3-K) values.
