Concept explainers
(a)
Interpretation:
The Gibbs energy for given reaction has to be calculated using given cell potential.
Concept Introduction:
The production of
The relation between the cell potential
(b)
Interpretation:
The Gibbs energy for given reaction has to be calculated using given cell potential.
Concept Introduction:
Electrochemical cells: Both oxidation and reduction occur at the same moment in an electrochemical cell. The oxidation process occurs at the anode while the reduction process occurs at the cathode in the cell. The concentration of the electrode (anode or cathode) in the half-cells and cell potential (voltage) can be calculated with the help of Nernst equation.
The production of electric current from spontaneous reaction occurring from the electrochemical cell is defined as galvanic cell.
The relation between the cell potential
