(a) For a free-radical addition polymerization with ki = 5 × 10−5 s−1, f = 0.5, kt = 2 × 107 dm3 mol−1 s−1, and kp = 3 × 103 dm3 mol−1 s−1, and with initial concentrations [M] = 2 mol/dm3 and [I] = 0.008 mol/dm3, calculate the following quantities for the early stages of the reaction when [M] and [I] are close to their initial values: [Rtot ∙], 〈DP〉, −d[M]/dt, and d[Ptot]/dt; assume that termination is by combination. (b) Repeat the calculations of (a) when termination is by disproportionation.
