Remember that in simple cases, where the slow step is the first step of the mechanism, the orders tell you what is taking part in the slow step. In this case, the …

WitrynaRate of a chemical reaction depends on the concentration of reactants/ products and time. Instantaneous rate is the best way to understand the rate of a reaction at a given point in time. Collision Theory. In order to understand the rates of reactions, various theories have been postulated and one important theory is the “Collision Theory”. Witryna2 lut 2024 · Add the order for all reactants together. The overall order of a reaction is the sum of each reactants' orders. Add the exponents of each reactant to find the overall reaction order. This number is usually less than or equal to two.
