The rate determining step (RDS) is the slowest step in a chemical reaction. It determines the rate of the reaction and therefore its speed. The RDS is important in chemical kinetics because it can be used to increase the speed of a reaction.
The RDS can be affected by various factors including the nature of the reactants the presence of catalysts and the temperature. The RDS can be changed by changing these factors. For example if the reactants are in a different state (solid liquid or gas) the RDS will be different. If a catalyst is present it can change the RDS by changing the activation energy of the reaction. And finally if the temperature is increased the RDS will be lower.
So what is the RDS? In a chemical reaction the RDS is the step that has the lowest rate. It determines the speed of the reaction and can be changed by changing the factors mentioned above.
