This reaction would only occur if it were driven by an expenditure of energy. The opposite reaction, on the other hand, would be the oxidation of lithium metal to give a lithium cation. That reaction would occur spontaneously, and would have a spontaneous "oxidation potential".Indices Commodities Currencies Stocks
