AIIMS 2017 Chemistry Nernst Equation Assertion Reason Question

Option D is correct because the assertion states that as the concentration of silver ions (Ag⁺) increases, the cell potential becomes more positive, which aligns with the Nernst equation. However, the reason provided does not accurately explain this relationship, as it fails to consider the role of the standard reduction potential and the logarithmic relationship between ion concentration and cell potential. Other options are not applicable in this context, as they do not provide relevant information or explanations related to the assertion and reason provided in the question. Understanding the Nernst equation is crucial, as it illustrates how concentration affects electrochemical cell potential, emphasizing the importance of both the concentration of reactants and the standard conditions.
