Chapter 14 # 107

Why do we use E(naught)=lnK for this problem, instead of E=E(naught)-lnQ in which Enaught would be zero (PH7)
I paraphrased the equations because I'm lazy

I think in this problem you use K instead of Q because when we are given a pH, we assume that the concentrations are at equilibrium. Basically, if a solution is at a certain pH, the concentrations are not going to change at that temperature.
