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

Using the following relatin and substituting the values jwe get
`E_(cell)^(@)=E_(cathode)^(@)-E_(anode)^(@)`
=-0.40 V-(-0.74 V)
=+0.34 V
