Concept: Understanding Standard Reduction Potential

CHEM-G8ZH4J

Which of the following must be controlled when determining the standard reduction potential (${E°}_{cell}$) of an electrochemical reaction?

Assume that ions in aqueous solution as well as gases are participants in the reaction.

Select ALL that apply.

A

Surface area of the electrodes used.

B

Temperature of the electrochemical cell.

C

Effective concentrations (i.e. activities) of participating ions.

D

Partial pressures of each participating gas.
