The equilibrium constant of the reaction...

The equilibrium constant of the reaction :
`Cu(s)+2Ag^(+)(aq) to Cu^(2+)(aq) +2Ag(s),E^(@)=0.46V` at 298 K is :

A

`2.0 xx 10^(10)`

B

`4.0 xx 10^(10)`

C

`4.0 xx 10^(15)`

D

`2.4 xx 10^(10)`

Text Solution

Verified by Experts

The correct Answer is:
C
`K="antilog "[(nE^(@))/(0.059)]="antilog" [(2 xx 0.46)/(0.059)]`
=antilog 15.593
`=3.9 xx 10^(15)`
`approx 4 xx 10^(15)`
