A The First Order Liquid Phase Exothermic Reaction A B Takes Place In A Batch Reactor At T 0 H All The Reactant A 1 (145.25 KiB) Viewed 12 times
a) The first-order, liquid-phase, exothermic reaction A + B takes place in a batch reactor. At t=0 h, all the reactant A is present in the reactor (no B present) at the required reaction temperature and the reaction is initiated by adding a small amount of catalyst. At t=0 h, an inert coolant flow to the reactor is initiated to control the reaction temperature. The reaction temperature is kept constant at 400 K, by varying the flowrate of the coolant. The coolant C temperature is 390 K.
Another way to keep the reactor temperature constant (at 400 K) is by using a cooling jacket where a boiling fluid is flowing to keep the reaction temperature constant. i) Calculate the amount of heat that the boiling fluid is removing (in J s-?) at the start of the reaction (t=0 h) [3] ii) Calculate the amount of heat that the boiling fluid is removing (in J s-l) at t=2 h after the reaction started [3] iii) When is the heat removal higher (at t= 0 hr or t= 2 hr) and why? = [2]
