Calculate the standard cell potential of...

Calculate the standard cell potential of galvanic cell in which the following reaction takes place
`2Cr_(s)+3Cd_(aq)^(+2)rarr2cr_(aq)^(+3)+3Cd_(s)`
Given `E_(Cr^(+3)//Cr)=-0.74(V)E^(@)_(Cd^(+2)//Cd)=-0.04(V)`

Text Solution

Verified by Experts

The correct Answer is:
0.34 V
`Cr|Cr^(3+)||Cd^(2+) |Cd`
`E^(Theta) = E_("(Cathode)")^(Theta) = E_("(Anode)")^(Theta)`
= `0.40 - (- 0.74) = 0.34 V`
