WebJan 4, 2024 · Table of Contents (click to expand) A galvanic or voltaic cell is an electrochemical cell that converts chemical energy into electrical energy. It achieves this by harnessing the energy produced by the redox reactions that occur within the cell. To understand this operation in detail, we must first understand what a redox reaction is. WebSep 17, 2014 · 1 Answer. Electrons flow from the anode to the cathode through an external wire. A common galvanic cell is the Daniell cell, shown below. The Zn (s) gives up its electrons to form Zn²⁺ (aq) ions. The … WebThis is because the copper is more electronegative than the zinc. The cell potential for this reaction is +1.10, since copper is being reduced and zinc is being oxidized, and if you plug this into the free energy equation for a cell ,ΔG= −n× F × EMF, you get ΔG= −2e-× (9.64 x 10^4 F) × (+1.10V) = -212 kJ. ray churchill attorney
