Unique Rate
Can someone clarify what unique rate laws are? I did not understand what Lavelle said during class about this. Thanks!

Re: Unique Rate
The unique rate is the instantaneous rate of change at any time t during the reaction. Unlike the average rate, which takes into account all of the times at which the reaction proceeds and averages it, the instantaneous rate is specific to a time and therefore it generates a different k value. The general equation used for the unique rate can be written as rate=d[R]/dt while the average rate is rate=∆concentration/∆t. Unique rate laws are specific to each reaction and are confined to a specific time.

Re: Unique Rate
In addition, when you calculate the unique rate, it is the same for all the reactants and products involved in the reaction.

Re: Unique Rate [ENDORSED]
For a reaction aA + bB -> cC + dD, where the lowercase letters are the stoichiometric coefficients and the uppercase letters are chemical species, the unique rate law is
This rate law is unique to the reaction and the same for all reactants and products in this reaction.
