By how much will the potential of half-cell `Cu^(2+)|Cu` change if the solution is diluted to 100 times at 298K?

A

Increases by 59 mV

B

Decreases by 59 mV

C

Increases by 29.5 mV

D

Decreases by 29.5 mV

Text Solution

Verified by Experts

The correct Answer is:
B
`Cu^(+2) (aq) + 2e^(-) to Cu(s)`
`E_(RP) = E_(RP)^(@) -(0.0591)/(2) log ""(1)/([Cu^(+2)])`
