How do we find the concentration for the K formula?

[OwenSumter_2F]

So with the equilibrium constant formula being K= [C]^c[D]^d/[A]^a[B]^b, how do we found those concentrations?

Hi! In some problems the concentration will be given to you. It will normally have the wording "at equilibrium, the concentration of ___ is ____." Those are the most straightforward problems.

In other problems where you will have to use an ICE box to calculate the equilibrium concentrations, the problem will either give you the initial concentrations or give you the initial value of moles along with the volume of the container, where you will have to use n/V.

The problems will clearly state whether or not you need an ICE box or if you can just plug in the values into the K equation based on the wording. Hope this helps :)

Awesome thank you, that clears up my confusion! :)
