▁models , ▁F c ▁is ▁dependent ▁on ▁changes ▁on ▁several ▁parameters ▁including ▁radical ▁size , ▁shape , ▁and ▁sol vent ▁vis cos ity . ▁It ▁is ▁reported ▁that ▁the ▁c age ▁effect ▁will ▁increase ▁with ▁an ▁increase ▁in ▁radical ▁size ▁and ▁a ▁decrease ▁in ▁radical ▁mass . ▁ ▁In iti ator ▁efficiency ▁▁ ▁In ▁free ▁radical ▁polym er ization , ▁the ▁rate ▁of ▁init iation ▁is ▁dependent ▁on ▁how ▁effective ▁the ▁initi ator ▁is . ▁ ▁Low ▁initi ator ▁efficiency , ▁ ƒ , ▁is ▁largely ▁attributed ▁to ▁the ▁c age ▁effect . ▁The ▁rate ▁of ▁init iation ▁is ▁described ▁as : ▁▁▁▁ ▁where ▁Ri ▁is ▁the ▁rate ▁of ▁init iation , ▁k d ▁is ▁the ▁rate ▁constant ▁for ▁initi ator ▁dis soci ation , ▁ ▁[ I ] ▁is ▁the ▁initial ▁concentration ▁of ▁initi ator . ▁In iti ator ▁efficiency ▁represents ▁the ▁fraction ▁of ▁primary ▁radical s ▁R · , ▁that ▁actually ▁contribute ▁to ▁chain ▁init iation . ▁Due ▁to ▁the ▁c age ▁effect , ▁free ▁radical s ▁can ▁under go ▁mut ual ▁de activ ation ▁which ▁produces ▁stable ▁products ▁instead ▁of ▁initi ating ▁propag ation ▁- ▁reducing ▁the ▁value ▁of ▁ ƒ . ▁ ▁References ▁ ▁Category : Ch em istry ▁theories <0x0A> </s> ▁The ▁ 2 0 1 6 – 1 7 ▁U M ass ▁Min ut emen ▁basketball ▁team ▁represented ▁the ▁University ▁of ▁Massachusetts ▁Am her st ▁during ▁the ▁ 2 0 1 6 – 1 7 ▁NCAA ▁Division ▁I ▁men ' s ▁basketball ▁season . ▁The ▁Min ut
