  1. The aroma from almonds and cherries is due in part to a compound called benzaldehyde. A graph of the natural logarithm of the vapor pressure of benzaldehyde vs. 1/temperature produces a straight line with a slope of –5478 K. What is the enthalpy of vaporization of benzaldehyde?

    (A) –5478 kJ/mol (B) +45.5 kJ/mol (C) –45.5 kJ/mol (D) –54.8 kJ/mol

(E) +49.3 kJ/mol

    Two students measured the vapor pressure of water at seven temperatures between 50.0°C and 80.0°C and made a graph of the natural logarithm of the vapor pressure versus the reciprocal temperature. Then the students fit their data to a straight line equation (R2 - 0.997): y = 13.66 - 5076.3x. From this data, calculate the enthalpy of vaporization for water.

    1. Calculate what the pressure of the air is in the flask at each of the temperatures for Trials 1 through 5. The temperature is related to the temperature (at constant volume and number of moles) through Gay-Lussac's Law. 2. Calculate the natural logarithm of the vapor pressures, ln(P/P^-), where P^- is 100 kPa. 3. Calculate the inverse of the absolute temperatures. 4. Prepare a graph (either by hand or in excel) with ln(P/P^-) plotted on the y-axis and 1/T...
