following reactions take place in a constant Volume semi-batch reactor as shown in Figure Q3 +BC+I+CO2rA=KACACB2KA=0.5(l/mol)2/min Initially, there is 4L of A in the reactor at concentration 4 mole/L. B is being added at a flow rate of 1.2L/min at concentration 4 mole/L. A,B,C and D are in liquid phase - CO2 is gas a. Write a mole balance equation for each species in the reactor. b. Calculate the concentration of each species in the reactor as a function of time c. Estimate the time of the reaction when CA=0.1CA
