Using the given data, a graph has to be prepared. Concept introduction: Electrochemical cell is a device capable of converting chemical energy into electrical energy or induces chemical energy by electrical energy. In the galvanic cell spontaneous redox reaction takes place. Redox reaction means the reaction in which the oxidation state of the atoms changes due to the occurrence of both reduction and its complementary oxidation reactions. The element under oxidation reaction loses electron whereas the element in the reduction gains electron. Battery: A battery is a device consisting of one or more cells that can be produce a direct current by converting by chemical energy into electrical energy. Rechargeable battery work because they use reaction are reversible, while non- rechargeable battery they use reactions are non-reversible.
