Given below the values below for the activation energies of benzoyl peroxide dissociation, styrene propagation, and styrene termination, and suppose all other parameters remain constant calculate the number average molar mass, initial radical concentration, and initial rate of polymerisation if the reaction is run at 66°C rather than 60°C.
EA dissociation = 115 kJ mol-1
EA propagation = 34 kJ mol -1
EA termination = 10 kJ mol-1
