Answer to Question #103570 in General Chemistry for James Okike

Question

What is unimoleculer reaction, bimolecular reaction, elementary reaction and overall reaction?

Answer 1

A monomolecular reaction is a reaction that occurs with a single molecule. For example, dissociation.

A bimolecular reaction is a chemical reaction in which 2 particles (molecules) participate.

An elementary reaction is a chemical reaction that directly occurs in the collision or decay of particles (molecules).

The overall reaction is, in fact, the reaction equation that describes all the chemical transformations that occurred with the particles (molecules) and, as a result, led to the formation of the final products. So, this is such a record of the entire chemical process, which reflects only the initial molecules (reagents) and final (products).
