thank you for the video!! i wonder if im just overthinking this, but at 11:27, if the concentration of Cu2+ was increased, why doesn’t that shift equilibrium to the right and actually form more products, which would cause Q to be bigger and Ecell to decrease?
Q would never become bigger than K. If reactants is increased at equilibrium, then the Forward reaction rate is increased because Q would be smaller. That increase would only lasted until the concentrations become constant
