How does temperature affect galvanic cells

WebHow does temperature affect a galvanic cell? Temperature affects the equilibria at each electrode (according to Le Chatelier’s principle). When the equilibrium of a half equation shifts, the half cell potential also shifts, which would change the electron motive force and overall voltage of the cell. WebStandard Electrode Potentials. In an electrochemical cell, an electric potential is created between two dissimilar metals. This potential is a measure of the energy per unit charge which is available from the oxidation/reduction reactions to drive the reaction. It is customary to visualize the cell reaction in terms of two half-reactions, an oxidation half …
