Asked by Eric
The vapor pressure, P, of a certain liquid was measured at two temperatures, T.
Represented in a table:
T (in Kelvin) ------- P(in kPa)
[325] --------------- [4.00]
[775] --------------- [8.59]
What is the enthalpy of vaporization for this liquid? (Delta H vap) in kJ/mol?
If you were going to graphically determine the enthalpy of vaporization (delta H vap) for this liquid, what points would you plot?
x1 =
x2 =
y1 =
y2 =
Determine the rise, run, and slope of these points.
much help would be greatly appreciated! thank you

Use the Clausius-Clapeyron equation. Here is a site that shows the plot.
