Type: MCQ-numerical-Hard-Class 12
The equilibrium constant of the reaction: Cu(s) + 2Ag⁺(aq) ⟶ Cu²⁺(aq) + 2Ag(s) ; E° = 0.46 V at 298 K is
A
2.0 × 10¹⁰
B
4.0 × 10¹⁰
C
4.0 × 10¹⁵
D
2.4 × 10¹⁰
Correct Answer
Option C
Detailed Explanation
The equilibrium constant can be calculated using the Nernst equation and the relation between E° and K. For this reaction, K is very large, indicating a strong tendency to form products.
