The reaction A --> B --> C has the rate equations. rA = 0.4 CA, rB = 0.3 CB - 0.4 CC Three tanks of different sizes are available. At the desired production rate, the residence times of 5 min, 10 min and 15 min, are maintained in the successive stages of the CSTR battery. The feed concentrations are CAo = 0.9; CBo = 1.2 and CCo = 0. Find the concentration of B in the effluent from each tank.
An elementary reaction of A + B ? C + D takes place in a 60 L semibatch reactor. The rate constant is 2 L/(mol-s). The reactor initially has 6 L of a liquid solution containing A at 0.1 mol/L. A stream of B containing 0.06 mol/L is fed in at 0.05L/s. Plot Ca, Cb, Cc, Cd and reactor liquid volume vs. time until the reactor is full. Please note the problem is meant to set up a system of...
