40 rate determining step energy diagram

Reaction Rates, Transition States, and Mechanisms The term "rate-determining step" or "rds" has a specific meaning. An rds is a step of a reaction the rate of which is equal to the rate of the overall reaction (conversion to final product (s)). The importance of a rate-determining step is that if the rate of that step is known, the rate of the overall reaction is known. How do you determine the rate-determining step of a ... How do you determine the rate-determining step in an energy diagram? Rate determining step (rds; rate limiting step): The mechanism step with the greatest activation energy (i.e., the slowest step) and therefore the step that has the greatest influence on reaction rate. Eact (step 2) > Eact (step 1) so rate (step 2) < rate (step 1).

Energy profile diagram for an exothermic reaction ... Hint: For the exothermic reaction, we can say that the step that requires the highest amount of potential energy will be the slowest step of the reaction. The slowest step of the reaction is taken as the rate determining step of the reaction. Complete answer: Here, we are given the energy profile diagram of a reaction.
