Every book I look at, they state(adsbygoogle = window.adsbygoogle || []).push({});

rate = -Δ[A]/Δt = k[A] , for A → B

From there, they go on to derive the concentration-time equation.

Well, my concern is what if we have: aA → B

Shouldn't "a" be accounted for in the derivation.

In other words, why don't we derive a more general equation using rate = -Δ[A]/aΔt = k[A]?

It seems like the book wants me to use ln[A]_t = -kt + ln[A]_0 even when I have aA → B

For some reason, it's always the chemistry books horrible at explaining things (unlike Biology and Physics).
