## Pseudo rate constant

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

### Pseudo rate constant

To find the rate constant for a first-order pseudo reaction, how do we find k'? It says in the course reader "slope" but I'm not sure which slope it's referring to.

### Re: Pseudo rate constant

Since it is the first-order pseudo reaction, then look at the plot of ln[A] vs Time. It should be a straight line and the slope of that line is -k.

So k' is -k?
