Webb12 feb. 2024 · The general rate law for a unimolecular elementary reaction (A → products) is rate = k [A]. For bimolecular reactions, the reaction rate depends on the number of collisions per unit time, which is proportional to the product of the concentrations of the reactants, as shown in Figure 14.19. black stitched shirts
