Given the standard electrode potentials $E^{0}_{Fe^{2+}|Fe} = -0.44 \, V$ and $E^{0}_{Fe^{3+}|Fe^{2+}} = 0.77 \, V$. If $Fe^{2+}$,$Fe^{3+}$,and $Fe$ are all present together,then:

  • A
    $Fe^{3+}$ will increase
  • B
    $Fe^{3+}$ will decrease
  • C
    $Fe^{2+}$ and $Fe^{3+}$ will not change
  • D
    $Fe^{2+}$ will decrease
