## writing rate laws

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

### writing rate laws

Is there a difference between rate law and the "rate of consumption of __"?

I believe that both phrases refer to the same equation. The second phrase is just specifying which reactants the rate law applies to.

### Re: writing rate laws

from my understanding: they both refer to the same equation; however, "the rate of consumption of ____" could change the sign. for example, if it is the rate of consumption of a reactant then it will be positive, but if it is the rate of consumption of a product then it will be negative.

rate of consumption is more specific but are essentially calculated in the same way. however it could have a different sign than the general rate law if it is specific to the reaction

Rate of consumption is just more specific than rate law because it determines whether the rate is positive or negative.
