Calculate the standard emf of a cell that uses the mg/mg2+ and cu/cu2+ half-cell reaction at 25°c. e o = v write the equation for the cell reaction that occurs under standard-state conditions. be sure to include the physical state of each species in the reaction.

Answer with Explanation:

We have to calculate the standard emf of a cell.

Consider

T=

Anode half reaction:

Cathode half reaction:

Overall reaction of cell :

Cathode :The electrode which gains electrons.

Anode: The electrode  which losses electrons.

We know that standard emf of the cell

Hence, the standard emf of  a cell=2.71 V
