Propagation in chemistry
WebPropagation of errors Whenever experiments are carried out involving more than one step, the uncertainties of each step must accumulate. It is not usually appropriate to add uncertainties in measurements of different types as absolute errors. Instead, the percentage error accrued at each measurement should be added together. WebPropagation requires many product molecules to be formed from a single radical species formed in the Initiation step. This can only occur if the Propagation steps are exothermic. Common termination steps include radical – radical coupling, disproportionation and …
