## Difference between each order of reaction

$aR \to bP, Rate = -\frac{1}{a} \frac{d[R]}{dt} = \frac{1}{b}\frac{d[P]}{dt}$

### Difference between each order of reaction

What's the difference between a zeroth, 1st and 2nd order reaction? Is it that they occur based on the number of reactants present? Also when having more than one reaction why does the overall reaction number the sum of all individual order reactions?

zero order reaction occurs at a constant rate. First order reaction rate is dependent on a reactant concentration and second order reaction rate is dependent on the square of a concentration of reactant.

It's based on the concentration not the amount. I'm also unsure why the overall reaction number the sum of all individual order reactions though in multiple reactions.
