## pseudo rate laws

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

### pseudo rate laws

when writing a pseudo rate law, why is the rate constant k denoted as k'(k prime)?

I think it's just to note that it's not the original k that you're dealing with: it includes other constants.

It is to denote that it is not the same k as the k in the overall rate law. I hope this helps!

It is a way of note that you are finding/using a different k value. I've also seen different k values expressed in other terms such as k2, where the original k value is expressed as k1.

The rate constant k is denoted as a k prime to indicate that it's inclusive of the other rate constants from other steps (i.e. k1, k2, etc)

To differentiate with the actual rate constant
