Homework Answers
Conditions for a standard electrochemical cell are :-
- Pressure of 1 atm Solution concentrations of \(1 \mathrm{M}\) Temperature of \(298 \mathrm{~K}\)
Explanation:-
An electrochemical cell is a device which convert chemical energy to electrical energy using chemical reactions. Examples is: Galvanic cell. It use redox reaction to generate electrical energy.
A standard electrochemical cell is a cell at standard state conditions. The conditions are 1 atm pressure, 298K \(\left(25^{\circ} \mathrm{C}\right)\) temperature and \(1 \mathrm{M}\) concentration of solutions.
For a galvanic cell at standard condition, the potential of that cell is,
$$ E_{c e l l}^{o}=E_{\text {cathode }}^{o}-E_{\text {anode }}^{o} $$
\(E_{\text {cathode- standard electrode potential of cathode }}^{O}\)
\(E_{\text {anode- standard electrode potential of anode. }}^{O}\)
This equation is only valid in standard condition of the cell.
