The standard EMF of a galvanic cell can be calculated from — Electrochemistry Chemistry Question

💡 Solution & Explanation

Standard electromotive force ($E^\circ_{cell}$) is an intensive property defined exclusively by the difference between the standard reduction potentials of the cathode and the anode ($E^\circ_{cell} = E^\circ_{cathode} - E^\circ_{anode}$). It is completely independent of the physical dimensions of the electrodes or the amounts of bulk materials.
