According to Vsepr theory, a molecule with the general formula ax4e2 will have a square planar molecular shape.The molecule of this geometry has their atoms which are positioned at the corners of the square on the same plan about a central atom.
If you are given the
standard potential for the reduction of X^2+ is +0.51 V, and the standard
potential for the reduction of A^2+ is -0.33, just add the two. The standard
potential for an electrochemical cell with the cell is 0.18V
