A reversible liquid-phase isomerization 2A 2B (elementary in both directions) is carried out isothermally in a 1000-gal CSTR (negligible pressure drop). The liquid (CB0 = 0, CAO = 5 M, solvent is water) enters at the top of the reactor and exits at the bottom. Experimental data taken at 350K shows the CSTR conversion to be 40%. The reaction is reversible with Keq = 9.0 (equilibrium constant) at 350 K, and AHx = -25,000 cal/mol. Assuming that the experimental data taken at 350 K are accurate and that for the forward reaction, Ea = 15,000 cal/mol, 1) Plot the equilibrium conversion vs. temperature. 2) Plot the conversion in the CSTR vs. temperature. 3) What CSTR temperature do you recommend to obtain maximum conversion? 4) If the CSTR is operated adiabatically, what is the optimum inlet temperature to maximize the conversion of A?
