When equilibrium is reached inside the two half-cells of the electrochemical cells, what is the net voltage across the electrodes?(a) > 1(b) < 1(c) = 0(d) Not definedI had been asked this question in unit test.Question is taken from Electrochemical Cells in section Electrochemistry of Chemistry – Class 12 |

Answer» CORRECT choice is (C) = 0 Best explanation: A half-cell is half of an electrochemical cell (electrolytic or galvanic), where either OXIDATION or REDUCTION occurs. At equilibrium, there is no TRANSFER of electrons across the half cells. Therefore, the potential difference between them is nil. |
