NEET Chemistry Nernst Equation MCQ Question
For the cell reaction : 2Cu⁺(aq) → Cu(s) + Cu²⁺(aq), the standard cell potential is 0.36 V. The equilibrium constant for the reaction is
2 × 10⁶
7.4 × 10¹²
4 × 10⁶
5.5 × 10⁸
Correct Answer
Detailed Explanation
The equilibrium constant K can be calculated using the Nernst equation: E° = (RT/nF)lnK. Substituting the given values and solving gives K = 7.4 × 10¹².
