What concentration of Benzoyl peroxide (k_d = 1.45 * 10^(-6) L/mol-s, 60 deg C) would be needed to polymerize a 1.00 M solution of styrene to a molecular weight of 2500 (Number average). Assume that termination occurs only by radical combination and that initiator efficiency is 100%. ( Styrene at 60 deg c has k_p = 0.176*10^(-3) L/mol-s and k_t = 7.2* 10^ (-7) L/mol-s )
