## Instantaneous Rate vs. Unique Rate [ENDORSED]

$aR \to bP, Rate = -\frac{1}{a} \frac{d[R]}{dt} = \frac{1}{b}\frac{d[P]}{dt}$

### Instantaneous Rate vs. Unique Rate

What is the difference between instantaneous rate and unique rate? I understand that instantaneous rate is the rate at a specific moment of time but what is unique rate and how is it relevant to rate laws?

A unique rate is a rate of appearance/disappearance of any of the species in a reaction divided by its stoichiometric coefficient, so it should be the same for each species. I think Lavelle mentioned that he would explain this in class tomorrow!
