हिन्दीThe standard enthalpy of fusion of ice is \( \Delta_{\text{fus}}H^\ominus = 6.00\text{ kJ mol}^{-1} \) at 273 K. What is the value of standard enthalpy of freezing of water at the same temperature?
View Answer & Solution
Correct answer · Option B
\( -6.00\text{ kJ mol}^{-1} \)
Explanation
Freezing is the reverse process of fusion. When the direction of a process is reversed, the magnitude of the enthalpy change remains the same but the sign is reversed (\( \Delta_{\text{freeze}}H^\ominus = -6.00\text{ kJ mol}^{-1} \)).
