If the half-cell reaction ` A + e^(-) rarr A^-` has a large negative reduction potential, it follows that .

Options

A. A is readily reduced
B. A is readily oxidized
C. `A^(-)` is readily reduced
D. `A^(-)` is readily oxidized.

Answer

D

Explanation

Gain of electrons is reduc tion and A has a large negative reduction potential . This means the reduction potential of A is very smaller. A is difficult to reduce to `A^(-)`. Therefore `A ^(-)` is easy to oxidise to A.
