Order Reaction/Rate Law

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

Order Reaction/Rate Law

Based on looking at a chemical reaction, what must be noticed to determine whether it be a First, Second, or Zeroth-Order reaction/rate law?

Re: Order Reaction/Rate Law

i think adding up the exponents in the rate law equation gives us the order of the reaction, or we could look at the way concentration changes as time increases (on a graph) ?

Re: Order Reaction/Rate Law

I think you use the rate law to find m and n which represent the order of the reactant.

Use the rate law, and add up the exponents of each reactant.
