Identifying zero order

Postby Glendy Gonzalez 1A » Sun Mar 04, 2018 11:35 pm

How can you identify a zero order reactant based on a table? Is there a "shortcut"?

There is no change in rate

You have to fully calculate the kinetic law. This can only be done if you know all of the elementary reactions involved.

Yes, when looking at a table you would first make sure the concentration of the reactant you are looking for is the only one changing between two experiments. If the concentration of the reactant changes and the rate does not change, then you know it is 0 order because the concentration of that particular reactant does not affect the rate of reaction.

If all other reactant concentrations remain the same and you change the concentration of the reactant of interest without changing the rate, then that reactant is zero order.

You need the table to identify 0 order reactions
