Calculate the value of $E^{\circ }$ and $\Delta G^{\circ }$ for the following reaction. $2Fe^{2+}(aq)+Br_{2}(aq)\rightleftharpoons 2Fe^{3+}(aq)+2Br^{-}(aq)$ $K=4.85\times 10^{10}$

Valence bond theory describes covalent bonds as the overlap of half-filled orbitals with electron pairs localized between two bonded atoms uses a combination of atomic orbitals to create molecular orbitals with electrons delocalized throughout the entire molecule creates bonding and anti -bonding interactions based on which orbitals are filled correctly predicts paramagnetism in molecules
