Question

According to the expression Δ G° = -nFE° , the cell reaction is spontaneous when (Notations and symbols carry their usual meanings) (A)  Δ G° is positive (B)  Δ G° is zero (C)  E° is negative (D)  E° is positive

Tardigrade Admin · Accepted Answer

For a spontaneous process, Gibb’s free energy change must be negative, so E° should be positive

Q. According to the expression $Δ G^{\circ} = - n F E^{\circ}$ , the cell reaction is spontaneous when (Notations and symbols carry their usual meanings)

$Δ G^{\circ}$ is positive

$Δ G^{\circ}$ is zero

$E^{\circ}$ is negative

$E^{\circ}$ is positive

For a spontaneous process, Gibb’s free energy change must be negative, so $E^{\circ}$ should be positive

Q. According to the expression ΔG∘=−nFE∘ , the cell reaction is spontaneous when (Notations and symbols carry their usual meanings)

ΔG∘ is positive

ΔG∘ is zero

E∘ is negative

E∘ is positive
