The equilibrium constant for the reaction, 

Cu(s) + 2A{g^ + }(aq) \rightleftharpoons C{u^{(2 + )}}(aq) + 2Ag(s),

{E^ \circ } = 0.46\text{ V}

at 298 K is:

View answer and explanation

Correct option: C

4.0 \times {10^{15}}

Option C (

4.0 \times {10^{15}}

) is correct because it is calculated using the relationship between standard EMF and the equilibrium constant,
