answer is A

the cell potential is the measure of the potential difference between two half cells in an electrochemical cell. the potential difference is caused by the ability of electrons to flow from one half cell to the other.

Answer:

Cell potential is defined as D. difference between reduction potentials of half cells.

Explanation:

The cell potential is calculated by taking the difference in the half reaction which is reductive and the half reaction which is oxidative.

Symbolically: E°cell = E°cathode − E°anode

Under standard temperature and pressure condition, the standard cell potential of hydrogen electrode is 0 V. The cell potential is obtained by subtracting because it is impossible to measure the exact single electrode potential hence it is measured in the form of difference.
