Re: Intermediates
No. One step reactions is a good example of when there is no intermediate. Whereas in a two step, there is typically an intermediate.

Re: Intermediates
Hi, no there won't always be intermediates involved in reactions. Intermediates are important in helping to carry out a reaction but are not always necessary. Also, even if there is an intermediate involved, it will not be present in the rate for the overall reaction.
Re: Intermediates
Not always. The specific phases that make up the whole process determine whether or not intermediates are present in a reaction mechanism. Chemical reactions frequently go through a number of basic phases, each of which involves the production and absorbance of molecules.
Re: Intermediates
No, there will not always be an intermediate to base the rate equation off of. The presence of intermediates in a reaction mechanism depends on the specific steps involved in the reaction pathway. Some reactions proceed through elementary steps that involve the direct conversion of reactants to products without the formation of intermediates. In such cases, the rate equation is based on the concentrations of the reactants themselves, rather than intermediates. However, in many cases, reaction mechanisms do involve the formation of intermediates. These are transient species that are formed in one step of the reaction mechanism and consumed in a subsequent step. In these cases, the rate equation is often based on the concentration of the intermediate because its formation and consumption determine the overall rate of the reaction.Whether or not an intermediate is present and whether it plays a role in the rate equation depend on the specific reaction mechanism and the steps involved in the reaction pathway. It is not a universal requirement for all reactions.
