### 15.3

In this problem in the textbook part c asks for the "unique rate of the reaction"? Is that just another way of asking what the overall rate of the reaction would be (aka the slowest rate)?

The unique rate is the instantaneous rate found using the ratios like (1/2)(dA/dt).

### Re: 15.3

Unique rate of reaction takes the form:

For the reaction aA -> bB + cC (where a, b, and c are stoichiometric coefficients),
Rate = $\frac{-1}{a} \frac{d[A]}{dt} = \frac{1}{b} \frac{d[B]}{dt} = \frac{1}{c} \frac{d[C]}{dt}$

Hope this helps!

### Re: 15.3

One thing I was confused on was where the 2 came from, so the 2 is because of the stoichiometric coefficient of the reactant? What if there was more than one reactant?
