![P5-6c A reversible liquid-phase isomerization A 2 B is carried out isothermally in a 1000-gal CSTR.
The reaction is second order in both the forward and reverse directions. The liquid enters at the top of
the reactor and exits at the bottom. Experimental data taken in a batch reactor shows the CSTR con-
version to be 40%. The reaction is reversible with Ke = 3.0 at 300 K, and AH, = -25,000 cal/mol.
Assuming that the batch data taken at 300 K are accurate and that E = 15,000 cal/mol, what CSTR
temperature do you recommend to obtain maximum conversion? [Hint: Read Appendix C and assume
AC = 0 in the appendix Equation (C-9)]:
K«(T) = K¢(T»JexpG-Đ)
