Slowest chemical reaction
WebbIn chemical kinetics, the overall rate of a reaction is often approximately determined by the slowest step, known as the rate-determining step (RDS or RD-step or r/d step) or rate … Webb28 juni 2016 · A step in a reaction mechanism is (kinetically) slow when it literally takes the longest time out of all the steps to occur. Another way to define it is... The rate of a mechanistic step is considered slow when it is most similar to the rate of the overall reaction. A simple way to think about this is considering how averages work.

WebbA reaction that occurs in two or more elementary steps is called a multistep or complex reaction. A reaction intermediate is a chemical species that is formed in one elementary step and consumed in a subsequent step. The slowest step in a reaction mechanism is known as the rate-determining step. Webb6 mars 2024 · The limiting reactant does affect the reaction rate, however it is not the only thing that determines the reaction rate (and thus the slowest step). The chemical nature of the reacting substances, the state of subdivision of the reactants, the temperature of the reactants, the concentration of the reactants, and the presence of a catalyst are all …

The reaction rate or rate of reaction is the speed at which a chemical reaction takes place, defined as proportional to the increase in the concentration of a product per unit time and to the decrease in the concentration of a reactant per unit time. Reaction rates can vary dramatically.
