Options
- A3.92 10¹²
- B3.92 10¹⁵
- C8.92 10¹⁷
- D8.92 10¹⁰
Correct answer
B. 3.92 10¹⁵
Step-by-step solution
Cu (s)+2 Ag ⁺(a q) Cu ²⁺(a q)+2 Ag (s)n=2, E_ cell ^ =0.46 ~V Now using the equation for E_ cell ^ aligned E_ coll ^ & = 0.0591 n K_c 0.46 & = 0.0591 n K_c K_c & = Antilog 15.5668 K_c & =3.92 10¹⁵ aligned
