The standard emf for the cell reaction, ...

The standard emf for the cell reaction,
`2Cu^(+)(aq)toCu(s)+Cu^(2+)(aq)`
is `0.36V` at `298K`. The equilibrium constant of the reaction is

A

`1.2xx10^6`

B

`7.4xx10^12`

C

`2.4xx10^6`

D

`5.5xx10^8`

Text Solution

Verified by Experts

The correct Answer is:
A
log`K_c=(nE_"cell"^@)/0.0591`
For the given reaction, n=1
log `K_c=(1xx36)/(0.0591)`=6.09
`K_c` = antilog 6.09 = `1.2xx10^6`
