## 15. 17 [ENDORSED]

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

### 15. 17

How do you know when a reactant is independent of the rate?

In experiments 1 and 4, the initial rate stays the same while the concentrations of A and B stay the same between the two experiments-yet, C changes between the two experiments. Thus, C does not contribute to the initial rate, because a change in the initial rate does not result from a change in C.

the values in experiment 1 and 4 the initial rate stays the same and the concentrations of A and B stay the same. C however changes between the 1 and 4 experiment so it doesn't contribute to the initial rate.
