Correct Answer: Option E

Explanation

The electrode potential of 2H\(^+\)(aq) / H\(_2\)(q) system is defined as 0 volt. This is because the standard hydrogen electrode(SHE) is defined as the reference point of measuring electrode potentials, and it is assigned a value of 0 volts. The SHE consists of a platinum electrode immersed in a solution with a hydrogen ion concentration of 1 M, and bubbled with hydrogen gas at a pressure of 1 atm.
