1
Q
What is an electrode potential
A
A charge difference between the metal and the solution
2
Q
What are standards conditions for a standard electrode potential
A
Conc of ions involved in half reaction must be 1 mol/l
Gas at 1 atmosphere
Temperature assumed 298K
3
Q
What is the reference half cell

5
Q
To calculate the standard free energy for cell reaction related to voltage
A
^G = -nFE
6
Q
What is a fuel cell
A
Generates electricity directly from a redox reaction
Reactant continually being added
Simplest is the hydrogen fuel cell
