Unfortunately, all of these ... 1. Therefore, the reaction is first-order in A or Band second order overall.In many reactions occurring in foods, the reactions can be describedmathematically as first-order even though the reaction ... overall. In A þ B ! P, the reaction is first-order in A or Band second order overall. In the reaction A þ A ! P, the reaction is second orderin A and second order overall. Thus, the overall order...
