Webb4 maj 2015 · The rate determining step is always the last step in a reaction mechanism. The stability/reactivity principle says that the more stable of two chemicals will be b. more reactive c. The reactivity/selectivity principle says that the more reactive of two chemicals will be less selective. d. WebbThe slowest step in a mechanism is called the rate-determining step (or rate-limiting step). For elementary reactions, rate laws (and reaction order) can be derived directly from the …
