WebOct 22, 2024 · HA(aq) + H2O(l) ⇌ H3O + (aq) + A − (aq) At first glance this gives an equilibrium constant of K = [H3O +][A −] [HA][H2O] But we can consider the water concentration constant because it is much greater than of acid that has ionized.
WebYou then multiply by ln (10) to have E° instead of E°/ln (10) and you find : E° = (b * ln10/n)log (K). He calculated b*ln10 and found 0.0592V. In the end, your equation is this : E° = (0.0592/n)log (K) When you use the equation G=-RTlnK, you … WebThis is how I solved using the natural log version: E = 0.0257/n *lnK is the simplified equation after you plug in your constants (see the Standard cell potential and equilibrium constant video for more info on this) We know that E is equal to 2.20V as solved in this video.
