How can quantum chemical calculations help explain the strength and stability of non-covalent interactions between molecules such as hydrogen bonding, van der Waals forces, and π-π stacking in biological systems? Provide specific examples from published literature where these calculations have been used to investigate non-covalent interactions in biomolecules such as proteins, nucleic acids, or carbohydrates.

Calculate the overpotential of an electrochemical cell where Zinc metal is used as an anode and Copper metal as a cathode. The concentration of Zinc ions in the half-cell is 1 M and Copper ions in the half-cell is 0.1 M. The temperature of the system is 25°C. (Given: Standard Reduction Potentials - Zn²⁺ + 2e⁻ → Zn(s) = -0.76 V and Cu²⁺ + 2e⁻ → Cu(s) = +0.34 V)

A student synthesized two coordination compounds containing the same metal ion, ligands, and donor atoms. However, the student found that the two compounds exhibited different physical and chemical properties. Explain the possible types of isomerism that could exist in these coordination compounds and how they can be distinguished.
