Solve the given problem while considering that the rate coefficients for initiator dissociation, propagation and termination can be replaced by the appropriate Arrhenius expressions in free-radical polymerization k_d = A_d exp (-E_d/RT); E_d = 126 kJ/mol,k_p = A_p exp (-E_p/RT); E_p = 34 kJ/mol,k_t = A_t exp (-E_t/RT); E_t = 10 kJ/mol compute the changes in the degree of polymerisation and the rate of the polymerisation caused by raising the temperature of polymerisation of styrene in C6H6, initiated by azobisisobutyronitrile from 60 0C to 70 0C. (Assume that the concentration of monomer and initiator and the values of f , q keeps same when the temperature rises)
