Webb3 sep. 2024 · Reaction rate determines how fast or how slow the reaction is. Reaction time is the time taken to complete a reaction to a certain extent. If the reaction rate is high for a particular reaction, then the reaction time is low. READ SOMETHING ELSE Table of Contentsshow 1Why is reaction time important in chemistry? Webb4 mars 2024 · By comparing the rate constants of the two steps, you can determine which step is faster and which is slower. The slowest step is the rate determining step, and thus it determines the speed at which the overall reaction proceeds. When coming up with your rate equation, you only have to look at the slowest step's reactants. Hope this helps! Top

Also, if the temperature is higher, more molecules will have enough energy to react, and the reaction will be faster. chirothin order

"WebbThe rate of the reaction is dictated by the slowest elementary step of the reaction. This step is called the “rate-determining step“. No matter how fast the speed of the other elementary steps are, the reaction cannot go faster than the slowest step. The diagram above is called a reaction coordinate diagram or energy profile diagram. " - Slow reaction rate
