Question: A first order liquid phase reaction is conducted adiabatically in a CSTR. The feed temperature is 300 K, the mean residence time is 1 h

A first order liquid phase reaction is conducted adiabatically in a CSTR. The feed temperature is 300 K, the mean residence time is 1 h and the reactant concentration in the feed is 2 mol/L. It is experimentally observed that the system has two stable operating temperatures of 302 K and 379 K for the given feed temperature. a) Derive R(T) and G(T) equations. b) Determine the temperature and conversion for the third, unstable steady state. Additional Data: CPO 500 cal/mol.K AHRX = -40 kcal/mol k=106 exp(-12238.05h-1 T T, K 300 310 320 330 340 350 G(T), cal/mol 754 2674 7897 17576 27998 34684 360 370 380 390 400 37806 39095 39616 39831 39923
