(4 points) You are producing poly-iso butylene (PIB) in a batch reactor at a constant temperature. To obtain a very low polydispersity, the initiator used is aluminum tri-chloride (AIC13) to produce a concentration of growing chains of 9 x 10 mol/L. It was previously determined that kp = 1.2 x 104 L(mol s)?. If the initial monomer concentration is 2.2 mol/L, x determine the time necessary to reach 99% conversion of the monomer
