Question 1. You will need to use a numerical solving software (e.g. MATLAB, Python, Excel) to solve this exercise. The reaction of A with B to give C : A+BCr=k1CACB is accompanied by the undesired side reaction: 2BDr=k2CB2 To minimize the amount of D that will be formed, an ideal semi-batch reactor will be used. The reactor will be operated isothermally at a temperature where the values of the rate constants are k1=0.50 L/molhr and k2=0.25L/molhr. The total volume of the reactor is 10,000L. The initial charge is 2000 L, containing 2.0mol/L of A,0.25mol/L of B, and no C or D. A solution containing 0.50mol/L of B and no A,C, or D is fed into the reactor at a rate of 1000L/hr for 7 hours, beginning immediately after the initial charge has been added. (a) What are the concentrations of A,B,C, and D in the reactor after 7 hours? (b) What is the value of the selectivity, SC/D for the overall process
