Ways of determining what order reactions are
Hello, I was wondering what are some ways of classifying what orders certain reactions are in? What are some key details that we can look for?

Re: Ways of determining what order reactions are
The order of a reaction is found by adding up the orders of all the reactants. To find the order of a reactant, we can use experimental data given to us. If an increase in concentration of a reactant doesn't change the reaction rate, then that reactant is a 0 ordered reactant. If the ratio of concentration change equals the ratio of reaction rate change when changing a single reactant, then that reactant is a 1st ordered reactant. If the ratio of concentration change equals the ratio of the reaction rate change squared, then that reactant is a 2nd ordered reactant.

Re: Ways of determining what order reactions are
Also looking at a graph of the data will give you an idea of what order a reaction is. For example, if the data looks linear, its first order.
