b) Differentiate between enthalpy driven and entropy driven reactions with the help of suitable examples.
| Criteria | Enthalpy-driven reactions | Entropy-driven reactions |
|---|---|---|
| Driving force | Change in enthalpy (∆H) is the driving force. | Change in entropy (∆S) is the driving force. |
| Nature of change | Typically involve energy exchange or heat transfer. | Typically involve changes in disorder or randomness. |
