## Rate law constant

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

### Rate law constant

Can rate law constant ever be negative?

i don't think the number itself can be a negative number, but k will be negative when it is the slope of a zero order or first order reaction.

The rate law constant can never be negative, but it can be a slope of negative k on the graphs of zero order and first order reactions.

Since rates are always positive values, the rate constant k is always positive.
