stoichiometry

[katherinemurk 2B]

How does stoichiometry come into kinetics? There are some questions in the book that ask about finding k constants when they give you the initial concentration of A but then give you a concentration of B at the some point in time?

For those problems, you have to set up an ICE box in order to find your final concentrations of [A] given the change in concentration of [B] so that you can plug it into the integrated rate laws for the respective orders.

[Laurence Tacderas 1K]

There may be problems where you need the final concentration of A to solve for the rate constant k or the time, but you are only given the final concentration of B. So then, given a balanced chemical equation, you would convert that final concentration in terms of A using stoichiometry.
