What is the difference between zero, first and second order reactions?

When we change the concentration of one of the reactants, zero, first and second reactions will all respond differently as to how much product is subsequently formed. The reaction order can tell us how impactful a certain reactant is.

No matter how we change the concentration of the zero order reactant, the reaction rate will not change. For a first order equation, the rate will linearly change when we change the reactant. For a second order when we change the reactant, it will change by the square of the reactant change.

Zero, first, and second order reactions also differ in their mechanisms, which Lavelle will talk about later in the course.

In each of the different order reactions, their reaction rates are affected by the concentration of reactants differently or not at all (in the case of zero order).

The differences are just the effect that the concentration of one reactant has on the overall reactant rate, that is, whether or not a change in concentration will have no effect on the rate, have a linear change, or cause a squared rate of change
