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. WebMay 5, 2024 · The potential difference is caused by the ability of electrons to flow from one half cell to the other. Electrons are able to move between electrodes because the chemical reaction is a redox reaction. A redox …
