(a)
Interpretation:
The standard cell potential for the given cell has to be calculated.
Concept Introduction:
An
Redox reaction: Redox reaction is a type of
The Standard Gibb’s free energy change and the standard cell potential are related as followed:
n - Number of electrons involved per equivalent of the net redox reaction in the cell
F - Faraday’s Constant (96500 C)
(b)
Interpretation:
The total cell potential when two given cells are connected in series has to be calculated.
Concept Introduction:
An electrochemical cell is a device in which a redox reaction is used to convert chemical energy into electrical energy. Such device is also known as the galvanic or voltaic cell.
Redox reaction: Redox reaction is a type of chemical reaction, where both the oxidation and reduction occur at the same time. In a redox reaction, one of the reactant is oxidized and the other is reduced simultaneously.
The Standard Gibb’s free energy change and the standard cell potential are related as followed:
n - Number of electrons involved per equivalent of the net redox reaction in the cell
F - Faraday’s Constant (96500 C)
(c)
Interpretation:
The cell that acts as voltaic cell and the one that act as electrolytic cell present in the given cell has to be identified when the given condition is applied.
