A solution of styrene (1.5 M) in THF is polymerized at 25oC by sodium naphthalene at a concentration of 3.2x10-5 M. Calculate the initial polymerization rate and the average degree of polymerization at the completion of the reaction. What fractions of the polymerization rate are due to free ions and contact ion pairs, respectively

![[M^-] = [K_d(M^-C^+])^{1/2}\\ \\\ [M^-] = [(1.5*10^{-7} \ mol/L )(3.20*10^{-5} \ mol/L ) ] ^{1/2}\\\\\ [M^-] = 2.19*10^{-6} \ mol/L](/tpl/images/0617/1547/2ad52.png)
![R_p = K_{\bar{p}} [M^-][M^+] + K_{\bar{p^+}}[M^-C^+][M^-]\\\\R_p = (6.5*10^4 \ L/mol.s)(2.19*10^{-6} \ mol/L)(1.5 \ mol/L)+(80 L/mol.s)(3.2*10^{-5} \ mol/L)(1.5 \ mol/L)\\\\R_p = 0.224 \ mol/ L.s + 0.00384 \ mol/L.s\\\\](/tpl/images/0617/1547/1e060.png)
