## 15.3 Unique Rate of the Reaction

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

### 15.3 Unique Rate of the Reaction

For 15.3c, why is the rate of formation of NO not taken into account in the unique rate of the reaction? Is it because the value of the rate is the same, regardless of which species is indicated? Also, wouldn't we have to multiply the rate of reaction of NO2 by -1/2 since it is decreasing? The solutions manual multiples the rate by a positive 1/2.

it is. You use the rate of formation you calculated and divide it by 2 because there is a coefficient of 2 in front of the NO
