Question

These are physical properties of an element: (A) Sublimation enthalpy, (B) Ionisation enthalpy, (C) Hydration enthalpy, (D) Electron gain enthalpy. The total number of above properties that affect the reduction potential is  (Integer answer)

Canvas Classes · Accepted Answer

Strategy:
 Identify the fundamental thermodynamic steps in the Born-Haber cycle for standard electrode potential in solution.

Factors for  potential:
1. Sublimation Enthalpy (A): Moving from solid lattice to gaseous atom. ✓
2. Ionization Enthalpy (B): Removing electrons from the gaseous atom. ✓
3. Hydration Enthalpy (C): Stabilizing the ion in water. ✓

Excluded Factor:
4. Electron Gain Enthalpy (D): This applies to anions (non-metals like gases) and is not part of the standard metal reduction
