NEET Chemistry Nernst Equation MCQ Question
Which of the following statements about electrolysis and electrode potentials is correct?
Electrolysis products depend on the oxidizing and reducing species and their standard electrode potentials.
Higher standard electrode potentials indicate that the reduced form is less stable than hydrogen gas.
The overpotential is not required for any electrochemical processes.
The electrolysis of molten NaCl produces NaOH and Cl2 gas.
Correct Answer
Detailed Explanation
Statement A is correct as the products of electrolysis are influenced by the oxidizing and reducing species present and their standard electrode potentials. Statement B is incorrect because higher standard electrode potentials indicate greater stability of the reduced form. Statement C is false since overpotential is often necessary for some processes. Statement D is incorrect as the electrolysis of molten NaCl produces sodium metal and Cl2 gas, not NaOH.
