Web1 de abr. de 2024 · The rate of a reaction is the speed at which a chemical reaction happens. If a reaction has a low rate, that means the molecules combine at a slower speed than a reaction with a high rate. Some reactions take hundreds, maybe even thousands, of years while others can happen in less than one second. WebA reaction rate can be reported quite differently depending on which product or reagent selected to be monitored. Given a reaction: aA + bB → cC + dD. the general rate for this reaction is defined as. rate = –1aΔ [A]Δt = -1bΔ [B]Δt = -1cΔ [C]Δt = 1dΔ [D]Δt. Equation 7.2.1 General Rate of Reaction.
