接下来要介绍的概念有一些类似:一个由多个步骤组合在一起的化学反应的反应速率就取决于速度最慢的那一步,即rate-determining step/rate-limiting step。 举个例子: (例子截图于Brown et al., ‘Chemistry, the Central Science.’) 知道了这个反应的steps,怎么determine rate law呢? 答案是根据慢的那一步来:Ra...

Also, in other examples the rate determining step (or indeed the mechanism as a whole) may change with concentration changes so again I'm not sure it's a valid approach all of the time.Order has nothing really to do with stoichiometry, sometimes it appears to be the same but that is ...

How can one determine the rate determining step of a chemical equation, and how is it different from the rate law? What is decay theory? what is distance decay? and what are some examples of it? What determines which type of radioactive decay occurs on a specific element (e.g. how do...
The rate-determining step (RDS) is a chemistry term for the slowest step in a chemical reaction. The rate-determining step is often compared to the neck of a funnel; the rate at which water flows through the funnel is determined by the width of the neck, not by the speed at which ...
The aim is to identify the reaction mechanism by constructing the rate law that it implies. This procedure may be simplified by identifying the rate-determining step of a reaction, the slowest step in a sequence that determines the overall rate. Thus, if the proposed mechanism is A → B ...
