3. There is a semi-batch reactor with 100 L X solution at a concentration of 2 mol/L. Inert solution (I) at a concentration of 0.5 mol/L is sent to this reactor at a rate of 0.75 L/min. Reaction takes place in isothermal conditions in this reactor. Since the rate constant (k) of the reaction is 0.018 L/mol.min; X Y a) What will be the concentrations of the components (X, Y, I) in the reactor after 30 min? b) What is the time at the moment when the conversion is 0.5. Note: You can assume that the density of the inert solution and X solution in the tank constant and equal.
