The efficiency of AIBN in initiating polymerization at 60C was determined by the following strategy. They measured Rp and v and calculated Ri=Rp/v. The constant kd was measured directly in the system, and from this quantity and the measured ratio Rp/v the fraction f could be determined. The following results were obtained for different concentrations of initiator. Using kd=0.0388h1, evaluate f from these data. (where f is your radical efficiency factor). ( 10 points)
