Question 7 What is the effect of increasing and decreasing the coolant temperature on the performance of a CSTR with an exothermic reaction? Answers: a. • When the coolant temperature increases, the reactor temperature will show an oscillatory behavior with time characterised by a run-away reaction spike • When the coolant temperature decreases, the reactor temperature wil decrease with time. smoothly reaching a lower steady state temperature b. . When the coolant temperature decreases, the concentration of the remaining reactant wil show an oscillatory behavior with time, first reaching a minimum corresponding to a reaction runaway where the reactor cools until the concentration builds again • When the coolant temperature increases, the concentration of the remaining reactant increases with time, smoothly reaching a higher steady state value c Either of the two given answers d. Both of the two given answers
