Reaction order

How do you get the overall order of a reaction?

You get the total order of the reaction by adding all the individual orders of the reaction!

The overall order of a reaction comes from the addition of the two exponents "n" and "m" which for single step reactions are equal to the stoichiometric coefficients of the reactants

To find n and m, use the "division method" we discussed in class. What this means is you use the equation rate = k[R]^n and plug in two of the experimental values so you have two equations with all the constants filled in except m and n. Then you divide them so that either m or n cancels, which will give you the value of the other variable. If this doesn't make sense, just know that its like a sytem of equations.

you can find that by adding all the individual reaction orders together
