following reactions take place in a constant Volume semi-batch reactor as shown in Figure Q3 $$+\mathrm{B}?\mathrm{C}+\mathrm{I}+{\mathrm{CO}}_2?{\mathrm{r}}_{\mathrm{A}}={\mathrm{K}}_{\mathrm{A}}{\mathrm{C}}_{\mathrm{A}}{\mathrm{C}}_{\mathrm{B}}^2{\mathrm{K}}_{\mathrm{A}}=0.5(\mathrm{l}/\mathrm{mol}{)}^2/\min$$ Initially, there is $$4\mathrm{L}$$ of $$\mathrm{A}$$ in the reactor at concentration 4 mole/L. $$\mathrm{B}$$ is being added at a flow rate of $$1.2\mathrm{L}/\min$$ at concentration 4 mole/L. $$A,B,C$$ and $$D$$ are in liquid phase - $${\mathrm{CO}}_2$$ 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 $${\mathrm{C}}_{\mathrm{A}}=0.1{\mathrm{C}}_{\mathrm{A}}$$
