3. The liquid phase reaction: 2A + B C+D is carried out in a semibatch reactor. The reactor initially contains 5 mol of B at a concentration of 0.015 kmol/m. There is no A in the reactor initially. A at an aqueous concentration of 0.03 kmol/m3 is fed to the reactor at a rate of 4 dm/min. The reaction is first-order in A and second-order in B with a rate constant k = 6,000 m/(kmol2 * min). RA= -K*CA CB? a. What is the initial volume of the reactor (hint: consider component B) b. Write the design equations in terms of Na, Nb, and V. Plot the conversion of B and volume over time out to 100 minutes. c. What is the final conversion of B after 100 minutes? d. What is the final volume of the reactor after 100 minutes
