Hydrogen bonding in water plays a key role in its physical properties. Assume that the energy required to
break a hydrogen bond is approximately 8 kJ/mol. Consider a simplified two-state model where a "formed"
hydrogen bond is in the ground state and a "broken" bond is in the excited state.
Using this model:
•
Calculate the fraction of broken hydrogen bonds at T = 300 K, and also at T = 273 K and T = 373 K.
•
At what temperature would approximately 50% of the hydrogen bonds be broken?
•
What does your result imply about the accuracy or limitations of the two-state model in describing
hydrogen bonding in water?
Finally, applying your understanding:
•
Would you expect it to be easier or harder to vaporize water at higher temperatures? Why?
If you were to hang wet laundry outside, would it dry more quickly on a warm summer day or on a
cold winter day, assuming humidity is constant?
