16. Consider the polymerization of styrene in toluene at 60°C initiated by di-t-butylperoxide fora solution containing 0.04 mol of initiator and 2 mol of monomer per liter. The initial rates ofinitiation, Ri, and propagation, Rp, are found to be 1.6 × 10^-10Ms^-1 and 6.4 × 10^-7Ms^-1,respectively, at 60°C.(a) Calculate fkd and kp/kt^1/2.(b) Assuming no chain transfer, calculate the initial kinetic chain length.(c) Assuming only disproportionation and under the conditions stated, the transfer con
