This document provides an overview of key concepts in electrochemistry, including: - Galvanic cells use spontaneous chemical reactions to generate electrical energy, while electrolytic cells use an applied voltage to drive nonspontaneous reactions. - Oxidation occurs at the anode and reduction at the cathode. Standard cell potential and Faraday's law relate the electrical work done to chemical reactions. - Faraday's law states that the amount of product formed during electrolysis is directly proportional to the charge passed, allowing calculations of moles reacted given current and time. - Standard cell potential and the Nernst equation describe how cell potential varies with reaction conditions versus under standard states.
