WebSummary. A reaction mechanism is the sequence of elementary steps by which a chemical reaction occurs. A reaction that occurs in two or more elementary steps is called a multistep or complex reaction. A reaction intermediate is a chemical species that is formed in one elementary step and consumed in a subsequent step.
