Order Reactions [ENDORSED]

What is the significance of the order of a reaction? Is it solely to determine which equations to use? Or does it offer more insight

[Molly Laviano 3N]

The order of a reaction describes the relationship between the concentration of a species and the rate of a reaction. By examining the overall order and the individual orders of the components of a reaction, we can see which concentrations influence the rate of the reaction. We are able to see if the concentration of one reactant is more or less influential than the concentration of another, or if the concentration of a reactant has no influence on the rate whatsoever (zero order).

The order also reveals how many molecules are involved. For example, a second order reaction involves two molecules colliding at the same time. This is why reactions of order 3 or more are uncommon because it is unlikely for 3 or more molecules to collide at the exact same time.

Order reveals how the concentrations of reactants relate to the rate

[Michael Lee 2I]

The order of reactions describes how the concentrations and the rate of the reaction are correlated/related.
