In a reaction Cr(2)O(7)^(2-) is reduced ...

In a reaction `Cr_(2)O_(7)^(2-)` is reduced to `Cr^(3+)`. What will be the concentration of `0.1 M K_(2)Cr_(2)O_(7)` in equivalent per litre?
`Cr_(2)O_(7)^(2-) + 14H^(+) + 6e^(-) to 2Cr^(3+) + 7H_(2)O`

Text Solution

Verified by Experts

The correct Answer is:

`0.936V`

`Cr_(2)O_(7)^(2-)+14H^(+)+6e^(-)to2Cr^(3+)7H_(2)O,1.33"volt"`
`E=1.33-(0.0591)/(6)log(((0.010^(2)))/((0.01)xx(10^(-3))^(14)))=1.33-(0.0591)/(6)log10^(-2)xx10^(52)`
`=1.33-(0.0591)/(6)log10^(40)=1.33-(0.0591)/(6)xx40=0.936"volt"`
