Question

Which statement is true in regard to a spontaneous redox reaction? (A)  textE textred is always negative (B) Ecell is always positive (C) Eox is always positive (D) Ered is always positive

Tardigrade Admin · Accepted Answer

A spontaneous process is one that occurs on its own, without any energy input from the outside.

Δ G = - v e

for spontaneous redox reactions.

Δ G = - n F E_{ce ll}

If

E_{ce ll}

is +ve, then

Δ G

will be –ve showing that cell reaction is spontaneous.

Q. Which statement is true in regard to a spontaneous redox reaction?

$E_{red}$ is always negative

$E_{ce ll}$ is always positive

$E_{o x}$ is always positive

$E_{re d}$ is always positive
