In the process to produce acetone from isopropyl alcohol (see process description on the CD), heat is supplied to the endothermic reaction using a Dowtherm A (or molten salt) loop and a fired heater. During the start-up of a new plant, it is found that the activity of the k_º) in the kinetics expression) is less than designed. How would you adjust the flow of heat transfer fluid (up or down) to compensate for this error? Explain your reasoning.
