Represent the cell and calculate the Standard e.m.f. of the cell having following cell reaction: `2Cr(s)+3Cd^(2+)(aq)to 2Cr^(3+)(aq) + 3 Cd(s) E^0 Cr^(3+)//Cr=-0.73 volt` and `E^0 Cd^(2+)//Cd=-0.40` volt

Text Solution

Verified by Experts

`E_("cell")^(@) = E_(Cd^(2+)//Cd)^(@)- E_(Cr^(3+)//Cr)^(@) = - 0.40 - ( - 0.73) = 0.33V`
