Question
### Boiling Pressure of Pure Acetone at Different Temperatures The following table shows the boiling pressure of pure acetone at different temperatures: | \( T \) (°C) | \( P_{\text{sat}} \) (mmHg) | |--------------|-----------------------------| | 0 | 68 | | 6 | 93 | | 12 | 130 | | 35 | 338 | | 50 | 643 | ### Problem Statement Find the enthalpy of vaporization of acetone, \( \Delta H^{\text{vap}} \) (kJ/mol), assuming that it is constant over this range of temperature. You may assume that \( Z^V - Z^L \simeq 1 \).
