Question:

Multiple choices only one is correct

One of the agreements of the scientific community regarding the electrochemical potentials is:
a) the standard hydrogen electrode acts as an anode
b) the potentials are expressed as a reduction
c) the sign of the reaction indicates the spontaneity of the reaction
d) activity coefficients are always considered


Answers

Ans : b) the potentials are expressed as a reduction

The electrochemical potentials of the species are expressed as their reduction potentials by default. So higher the reduction potential , more easily it will get reduced , and hence stronger will be the oxidizing agent.

So the species lying at the top of the electrode potential table are stronger oxidizing agents than the ones lying below them in the table.
