Now, before we can talk about cell potential and its connection to the Nertz equation, it's important to revisit the idea of our reaction potion. Now recall that the reaction potion which uses the variable Q, is a ratio of product to react and concentrations at a particular time, and we're going to say it can be calculated by setting up an expression and ignoring solids and liquids.

Remember, like your equilibrium constant K, we only care about gaseous and aqueous aqueous species. Now how does this relate to electoral count? Well, we're going to say here that for electrochemical sounds it helps to find the Max potential at the exact moment the cell serpent is connected because as we know overtime our voltage is going to decrease as our battery, as our electrochemical cell overall degrades, right.

So this is where the reaction quotient comes into play. It helps us to find that exact moment in which our voltage is going to be at its highest.
