For styrene polymerized at 70ᵒC, monomer concentration is 7.85mol/l and the value of the ratio (kp2/kt) is 0.0015 l/mol-s. What is the rate of polymerization reaction, if the chain length is 300?

For styrene polymerized at 70ᵒC, monomer concentration is 7.85mol/l and the value of the ratio (kp2/kt) is 0.0015 l/mol-s. What is the rate of polymerization reaction, if the chain length is 300? Correct Answer 0.046

The kinetic chain length expression is given by, v= (kp2/kt)(2/Rp) Substituting the values we get, Rp as 0.046.
