Question

Which of the following affects cell potential?

a. the standard cell potential value
b. the electronegativity of the elements in the electrodes
c. the volume of the solutions
d. all of the above

Answer 1

Answer:

the standard cell potential value

Explanation:

For every cell, we can calculate its standard electrode potential from the table of standard electrode potentials listed in many textbooks.

However, from Nernst's equation;

Ecell= E°cell - 0.0592/n log Q

Hence the standard cell potential (E°cell) affects the value of the calculated cell potential Ecell from Nernst's equation as stated above.
