WebA reaction mechanism is the sequence of elementary steps by which a chemical reaction occurs. Many reaction mechanisms contain one step that is much slower than the others; this step is known as the rate-determining step. If the rate-determining step is the first step in a mechanism, the rate law for the overall reaction can be derived directly ... WebJan 25, 2024 · How do you determine the order of a reaction example? Ans: There is a relation between the reaction rate and the concentration of a reactant by the rate constant. Furthermore, its representation is by the letter K. Moreover, there is a constant change in the rate as the temperature changes.
