The vapor pressure of the ethanol is calculated by remembering that the total pressure in the flask is the sum of the pressure of the air in the flask and the vapor pressure of the ethanol. Calculate the natural logarithm of the vapor pressures, In(P/PⓇ), where PⓇ is 100 kPa. Convert all your temperature readings to Kelvin. Calculate the inverse of the absolute temperatures. Prepare a graph (either by hand or in Excel) with In (P/P) plotted on the y-axis and 1/T (K-¹) plotted on the x- axis. Follow all the rules for properly preparing a scientific graph. Remember to turn in your graph with your report. Determine the line of best fit for your data. Calculate the slope of this line. From the slope calculate the enthalpy of vaporization.
