Question

Hello, can you solve it with explanation ? thnx.

The equation below describes the degree of polymerisation for a radical
polymerization (ignoring side reactions such as diproportionation) Rp is the rate of
polymerization, what are CM and C₁?
1/X = R₁/2R + CM+C₂[I]{[M]
CM = 8.0x10-5
C₁ = 3.2x10-4
Calculate the expected M, of a polymer when 1.0 M Styrene solution in toluene is
reacted with 0.01 M di-tert-butylperoxide. The initiation rate (R₁) is 4.0 x 10-11 mol L s
1 and polymerization rate is 1.5 x 10-7 mol L s¹. Use the equation from Q8.
Repeat the calculation for an initiator concentration of 0.3 M. Why is it lower?
