### Unique rates

What are unique rates? Do we need to know that for test 3?

### Re: Unique rates

Dr. Lavelle just mentioned unique rates last week. Whereas average rate is the change in concentration over the change in time, and is different for each product and reactant, unique rate is the same for every product and reactant in that specific, or "unique", reaction. To find unique rate:
For a reaction aA --> bB + cC (where a b and c are stoichiometric coefficients)
unique rate= (-1/a)*d[A]/dt = (1/b)*d[B]/dt = (1/c)*d[C]/dt where d[]/dt is the instantaneous rate at that time

### Re: Unique rates

Dr. Lavelle also summarizes information regarding unique rates in this thread below and, in general, it is a very informative thread:

Yes this could potentially and most likely will be on the test.

### Re: Unique rates

And since there are assigned homework problems involving unique rates i assume it can be asked on the test

Return to “Method of Initial Rates (To Determine n and k)”
