Rate Determining Step Chemtalk Using molecularity to describe a rate law. the molecularity of an elementary reaction is the number of molecules that collide during that step in the mechanism. if there is only a single reactant molecule in an elementary reaction, that step is designated as unimolecular; if there are two reactant molecules, it is bimolecular; and if there are three reactant molecules (a relatively rare. 3.2.3: rate determining step. page id. the rate determining step is the slowest step of a chemical reaction that determines the speed (rate) at which the overall reaction proceeds. the rate determining step can be compared to the neck of a funnel. the rate at which water flows through a funnel is limited determined by the width of the neck of. The equation for the overall reaction is obtained by adding the two elementary reactions: 2no(g) cl2(g) 2nocl(g) to derive a rate law from this mechanism, first write rates laws for each of the two steps. rate 1 = k1[no][cl2] for the forward reaction of step 1 rate − 1 = k − 1[nocl2] for the reverse reaction of step 1 rate 2 = k2[nocl2. The rate determining (slower) step gives a rate law showing second order dependence on the no 2 concentration, and the sum of the two equations gives the net overall reaction. in general, when the rate determining (slower) step is the first step in a mechanism, the rate law for the overall reaction is the same as the rate law for this step.

The rate determining (slower) step gives a rate law showing second order dependence on the no 2 concentration, and the sum of the two equations gives the net overall reaction. in general, when the rate determining (slower) step is the first step in a mechanism, the rate law for the overall reaction is the same as the rate law for this step. The rate law? before answering the question, it is necessary to consider the existence of a special reaction in the mechanism known as the rate determining step. rate determining step (rds): the slowest step in the reaction. for example, in the two step reaction above, each of the equations has its own reaction rate. the one that is slowest is. Or reaction that describes a process as it occurs at the molecular level. a single reaction event which occurs in one simple atomic or molecular collision. most reactions do not occur in a single elementary step. derive corresponding rate laws. compare with experiments. repeat as needed.
