Multiple steady stales

The phase plane of C vs. T shows a separairix. [2nd Ed.. P8-22) A second-order reaction with multiple steady stales is carried out different solvents. 

P8C-3 In an article on the kinetics of sucrose inversion by invertase with multiple. steady states in a CSTR [Chem. Eng. Commun.. 6, 151 (1980)], consider the following challenges Are the equations for Kj and K correct If not, what are the correct equations for these variables Can an analysis be applied to this system to deduce regions of multiple steady stales ... 

With B - 0,2 and En 30.0. Figure 12.4 shows the (X,S) space where multiple steady stales occur. Only the upper and lower values of X are stable, while intermediate values arc unstable. It would be interesting to know when the system will jump from one branch to another. This stability problem may be controlled by the direction and magnitude of fluctuations. Figure 12.4 is obtained from the following MAT HEMATIC A code ... 

Figure 7-18 Since tiie reactions in the ACC are sh ongly exothermic, hie catalyst can exhibit multiple steady states as hie catalyst suddenly lights off as the car is staled aid the terrqieratae rises to the ignition temperatiue, vdnch then causes a rapid increase in temperature.
