The appropriate arrhenius expressions

Reference no: EM13837963

Assuming that in free-radical polymerization the rate constants can be replaced by the appropriate Arrhenius expressions:

k_d = A_dexp(-E_d/RT)

k_p = A_pexp(-E_p/RT)

k_t = A_texp(-E_t/RT)

Calculate the changes in the rate of polymerization and the degree of polymerization caused by increasing the temperature of polymerization of styrene in benzene initiated by AIBN from 60C to 70C given that:

E_p = 34 kJ mol^-1

E_t = 10 kJ mol^-1

E_d = 126 kJ mol^-1

Assume that the concentration of monomer and initiator and the values of f and q remain unchanged when the temperature is increased.
