A half-cell reaction is given. The value of E ° for the given cell reaction is to be calculated. Concept introduction: The relationship between reduction potential and standard reduction potential value and activities of species present in an electrochemical cell at a given temperature is given by the Nernst equation. The value of E cell is calculated using Nernst formula, E = E ° − ( R T n F ) ln ( Q ) At room temperature the above equation is specifies as, E = E ° − ( 0.0591 n ) log ( Q ) This relation is further used to determine the relation between Δ G ° and K , Δ G ° and E ° cell . Solubility product is applied only for those ionic compounds that are sparingly soluble. The product of solubility of ions is called solubility product and solubility is present in moles per liter. To determine: The value of cell potential E ° for the given cell reaction.

Definition Definition Study of chemical reactions that result in the production of electrical energy. Electrochemistry focuses particularly on how chemical energy is converted into electrical energy and vice-versa. This energy is used in various kinds of cells, batteries, and appliances. Most electrochemical reactions involve oxidation and reduction.

Interpretation Introduction
Interpretation:
A half-cell reaction is given. The value of
E° for the given cell reaction is to be calculated.
Concept introduction:
The relationship between reduction potential and standard reduction potential value and activities of species present in an electrochemical cell at a given temperature is given by the Nernst equation.
The value of
Ecell is calculated using Nernst formula,
E=E°−(RTnF)ln(Q)
At room temperature the above equation is specifies as,
E=E°−(0.0591n)log(Q)
This relation is further used to determine the relation between
ΔG° and
K ,
ΔG° and
E°cell.
Solubility product is applied only for those ionic compounds that are sparingly soluble. The product of solubility of ions is called solubility product and solubility is present in moles per liter.
To determine: The value of cell potential
E° for the given cell reaction.
