1. The maximum allowable temperature for a reactor is 800K. At present our operating set point is 780
K, the 20K margin of safety to account for fluctuating feed, sluggish controls, etc. Now, with a more
sophisticated control system we would be able to raise our set point to 792K with the same margin of
safety that we now have. By how much can the reaction rate, hence, production rate, be raised by this
change if the reaction taking place in the reactor has an activation energy of 175 kJ/mol? (05 marks)
2. What are reactions of shifting order? Give brief. (03 Marks)

rate of our feed for the same 90% conversion? (08 Marks)
2. The kinetics of the aqueous-phase decomposition of A is investigated in two mixed flow reactors in series,
the second having twice the volume of the first reactor. At steady state with a feed concentration of 1.0
mol-A/L and mean residence time of 96 sec in the first reactor, the concentration in the first reactor is 0.5
mol-A/L and in the second is 0.25 mol-A/L. Find the kinetic equation for the decomposition. (08 Marks)
3. Substance A in the liquid phase produces R and S by the following reactions:
The feed (CA0 = 1.0, CR0 = 0, CS0 = 0.3) enters two mixed flow reactors in
series (τ1 = 2.5 min, τ2 = 10 min). Knowing the composition in the first
reactor (CA1 = 0.4, CR1 = 0.2, CS1 = 0.7), find the composition leaving the
second reactor. (10 Marks)
