Order reactions

How do you know if a reaction is zeroth, first or second order if it is not specified?

Usually, some sort of experimental data will be given to us so that we can figure out what order the reactants are.

You can look at the units for k if it is given or the rate law

You can infer from either the units of the rate constant, or the experimental data will tell you.
