Methyl methacrylate was polymerized at a mass concentration of 200g dm^-3 in toluene using azobisisobutyronitrile as initiator at a mass concentration of 1.64 X 10^-2 g dm^-3 and a reaction temperature of 60 degree C. Calculate the initial rate of polymerization and the molar mass of the poly(methyl methacrylate) formed in the initial stages of the reaction given that the relevant rate coefficients at 60 degrees C are:

Initiator dissociation: k sub d= 8.5 X 10 ^-6 reciproical seconds

Propagation k sub p= 8.33 dm^3 mol^-1 s^-1

termination, k sub t= 9.3 X 10 ^6 dm ^3 mol ^-1 s^-1

transfer to monomer k sub trm= 3.93 X 10 ^-3 dm^3mol^-1s^-1

Transfer to solvent k sub trS= 7.34 X 10 ^-3 d, ^3 mol ^-1 s^-1

Assume that the initiator efficiency f=0.7 that the termination by combinaition is negligible, and that the density of the initial solution of MMA in toluene is 860 g dm^-3

using excel Plot the probability mass function (PMF) and the cumulative distribution function (CDF) of 3 random variables following (1) binomial distribution [p,n], (2) a geometric distribution [p], and (3) Poisson distribution [?]. You have to consider two sets of parameters per distribution which can be chosen arbitrarily. The following steps can be followed: Setp1: Establish two sets of parameters of the distribution: For Geometric and Poisson distributions take two values of p (p1 and p2) and take two values...
