In a polymerization reaction of styrene (with the concentration of 2 M) in 2 liter cyclohexane solvent. The polymerization is initiated by the thermal decomposition of BPO initiator (with the concentration of 2 x 10-3 M) at 75 °C.)

(kp =1 x 10 liter/mole-sec, kt = 7.0 X 10 liter/mole-sec, f = 0.7 and the half-life time of the initiator at 75 °C is 4 hours and 85 °C is 1.5 hours).

Q: (d) How long will it take to prepare 1.04 Kg of polystyrene?
