Rate-determining step
rate-determining step also known as the RDS or rate-limiting step. In chemical kinetics, the overall rate of a reaction is often approximately determined by the slowest step, For a given reaction mechanism, the prediction of the corresponding rate equation (for comparison with the experimental rate law) is often simplified by using this approximation of the rate-determining step.
In principle, the time evolution of the reactant and product concentrations can be determined from the set of simultaneous rate equations for the individual steps of the mechanism, one for each step. However, the analytical solution of these differential equations is not always easy, and in some cases, numerical integration may even be required.[1] The hypothesis of a single rate-determining step can greatly simplify the mathematics. In the simplest case, the initial step is the slowest, and the overall rate is just the rate of the first step.
Yes, it is not 1-2 steps, the rate-determining step 1st step in the chemical reaction from these steps we can determine those rates of reaction. the below figure shown rate-determining step.
