The equation for calculating E cell is E cell = E cathode - E anode, where E cathode is the reduction potential of the cathode and E anode is the oxidation potential of the anode.
The reduction potential of the cathode can be found in a standard reduction potential table, while the oxidation potential of the anode can be calculated by reversing the sign of the reduction potential.
Calculating E cell allows us to determine the voltage or potential difference of an electrochemical cell, which can provide information about the spontaneity and direction of a chemical reaction.
To calculate E cell at a specific temperature, you can use the Nernst equation, which takes into account the temperature dependence of the reduction potential.
Yes, E cell can be negative if the anode has a higher reduction potential than the cathode. This indicates a non-spontaneous reaction and a reverse direction of electron flow.
