I am addressing specifically:
AAMC 7 PS#24
My question is how do we determine rate law? I understand we compare the relationship b/t reactant concentrations to rates while maintaining other reactant concentrations constant, but what if we were not given rates to compare but rather we had the additional data of the rate constant and the change in concentration of a reactant (another reactant) over time.
Since the change in concentration of the other reactant over time is the rate can't we just compare the relationship between how the reactant (one that I'm trying to find the rate of) changes and the change in concentration of the other reactant over time?
The answer says we have to divide the change in concentration of the other reactant over time by the rate constant AND then compare that to the change in reactant (one I'm looking for) concentration?
Why?
Thanks.
If you're confused, it'd be best to consult the AAMC question to better understand my question. It's hard to explain.
