α RC. = r RC.,p r RC.,p + r RC.,f + r RC.,t r RC.,p = r RC. add + r RC.+O 2 r RC.,f = r RC. Habs r RC.,t = r RC. recomb + r RC. disprop + r RC. cyc + F out, RC. + F evap, RC. (26) where r RC. stands for the flux of carbon-center radical consumption by a certain reaction type in moles per second, indicated by its subscript (radical addition 'RC. add'; hydrogen atom abstraction 'RC. Habs'; radical recombination 'RC. recomb'; radical disproportionation 'RC. disprop'; combination with oxygen 'RC.+O 2 '; cyclic ether formation 'RC. cyc'), F out, RC. is the flux of carbon-center radicals leaving via the liquid outlet flow, and F evap, RC. is the evaporation flux of carbon-center radicals. Note that hydrogen atom abstraction terminates the growing chain and initiates a new chain.
