Question

Which statement defines reduction potential when considering a pair of half-cell reactions?

The half-reaction with the greater SRP has a greater tendency to gain electrons.
The half-reaction with the lower SRP has a greater tendency to gain electrons.
If each half-reaction has an SRP greater than zero, there will be two reduction reactions.
If each half-reaction has an SRP less than zero, there will be two oxidation reactions.

Answer 1

ANSWER: The correct answer is A. The half-reaction with the greater SRP has a greater tendency to gain electrons.

Answer 2

The half reaction with the the greater SRP has a greater tendency to gain electrons is the definition of reduction potential when considering a pair of half cell reactions.This reduction potential is measured against hydrogen electrode which is standard electrode.
