Calculate the E _ cell ^o for Zn _ ( s ) | Zn _ ( IM ) ⁺ | | Cd _ ( IM ) ⁺ | Cd _ ( s ) at 25^ C [ E _ Zn ^ =-0.763 ~V ; E _ Cd ^ =-0.403 ~V ]
Options
- A0.36 ~V
- B1.17 ~V
- C-0.36 ~V
- D-1.17 ~V
Correct answer
A. 0.36 ~V
Step-by-step solution
For the given cell reaction, anode is Zn and cathode is Cd . aligned E _ cell ^o & = E _ cathode ^ - E _ anode ^0 & =-0.403-(-0.763) & =0.36 ~V aligned
