Develop a spreadsheet for the polymerization of vinyl acetate at 75C using p-chlorobenzoyl peroxide as an initiator. Use the following data: - vinyl acetate is being polymerized in an inert solvent at an initial concentration of 8mol/L - The initial concentration of the initiator is 0.01mol/L - Use information given in notes to calculate the necessary rate constants (kd,kp and k1 ) - Assume f=0.5 - Assume termination by coupling only A) Calculate the following quantities every 0.5 hours between t=08 hrs.: - p (conversion) - [M] (monomer concentration) - [I] (initiator concentration) - XA (number-average degree of polymerization) B) Include a graph of conversion (p) vs. time, and another graph of Xavs.time.. C) Assume the reactor was initially filled with 100 liters of solution. Calculate the initial mass (kg) of monomer before the polymerization began. D) Calculate the mass of polymer produced after 1 hour. Hint: the mass of polymer produced equals the mass of monomer consumed. Use the definition of comversion (p) to help you calculate this
