STANDARD Chemistry Nernst Equation MCQ Question
In a cell reaction, Cu(s) + 2Ag⁺(aq) → Cu²⁺(aq) + 2Ag(s) E° cell = +0.46 V. If the concentration of Cu²⁺ ions is doubled then E° cell will be
doubled
halved
increased by four times
unchanged
Correct Answer
Detailed Explanation
E° cell is determined by the standard electrode potentials and is independent of the concentration of ions. Therefore, it remains unchanged.
