| - | In modelling used to match complex oscillations, wc attempt to allow f (the number of bromide ions produced as two cerium ions are reduced) to be a function of the instantaneous concentrations of other species, such as HOBr. Process C sees the blue change to red and resets the chemical clock for the next oscillation. | + | In modelling used to match complex oscillations, wc attempt to allow f (the number of bromide ions produced as two cerium ions are reduced) to be a function of the instantaneous concentrations of other species, such as HOBr.
