The reaction 2A + B → C obeys the rate law –rB = kCB2, where k = 0.25 L/mol.s at 75˚C. A is available as a 1.5 M solution and B as a 1 M solution.

a). A 26 L/s stream of solution A and 30 L/s stream of solution B are combined just before being introduced into a CSTR. If a 150 L reactor is available, how many mole/h of C could be produced?

b). You receive some financing to increase C production. After some investigation, you find you could either add a second 150 L CSTR in series with the first or add another heater to increse the reactor temperature to 85 ˚C. Which is the best option? (The reaction has an activation energy of 70 kJ/mol.)
