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

4
Q

What is an oxidising agent

A

Electron acceptor p

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
