Chapter 8 #67a

Hi everyone! Does anyone know why the problem uses the heat of vaporization of water at 25 degrees celsius instead of the standard one? The problem does not state anything about the temperature. Thank you!

I am not sure if I am understanding your question about the problem completely, but the value given in the table for the standard enthalpy of formation for water is the same value calculated in the solutions manual for the problem. I do not think any of the problems will be as easy as looking at the table and writing down the value for enthalpy given, but rather they will have us utilize one of the three different ways to calculate the enthalpy. In this case, the solution manual used the bond enthalpies to determine the final value, but in the end it is all the same under the same conditions.

Thank you!
