The equilibrium constant of the reaction: Cu _ (s) +2 Ag _ (a q) ⁺ Cu _ (a q) ²⁺+2 Ag _ (s) E ^ o =0.46 ~V at 298 ~K is:

Options

  1. A2.4 10¹⁶
  2. B4.0 10¹⁰
  3. C4.0 10¹⁵
  4. D2.4 10¹⁰

Correct answer

C. 4.0 10¹⁵

Step-by-step solution

As E _ cell ^0= 0.0591 n K _c aligned & 0.46= 0.0591 2 K _c & K _c= 2 0.46 0.0591 =15.57 & or K _c= Antilog 15.57=3.7 10¹⁵ aligned
