WebReaction Order To reiterate, the exponents x and y are not derived from the balanced chemical equation, and the rate law of a reaction must be determined experimentally. These exponents may be either integers or fractions, and the sum of these exponents is known as the overall reaction order. WebFeb 12, 2024 · The reaction order is the relationship between the concentrations of species and the rate of a reaction. Introduction The order of a rate law is the sum of the exponents of its concentration terms. Once the rate law of a reaction has been determined, that …
