3. Create a column 1/Temperature (in units of 1/K ). To do this: a. Choose New Calculated Column from the Data menu. b. Enter "1/Temperature" as the Name, "1/Temp" as the Short Name, and "1/K" as the Unit. c. Enter the correct formula for the column (1/Temperature) into the Equation edit box. To do this, type in " 1 " and "p". Then select "Temperature Kelvin" from the Variables list. In the Equation edit box, you should now see displayed: 1 " Temperature". d. Click 4. Create a column ln Vapor Pressure. To do this: a. Choose New Calculated Column from the Data menu. b. Enter "ln Vapor Pressure" as the Name, "In V Press" as the Short Name. You do not need to enter a unit. c. Enter the correct formula for the column into the Equation edit box. Choose "ln" from the Function list. Then select "Vapor Pressure" from the Variables list. In the Equation edit box, you should now see displayed: In("Vapor Pressure"). Click d. Click on the vertical axis label and choose In Vapor Pressure. e. Click on the horizontal axis label and choose 1/Temperature. f. Autoscale the graph by clicking on the Autoscale button, [A, on the toolbar. g. Click the Linear Fit button, 5. From the Regression Statistics option, find the slope, m, of the regression line. 6. Use the slope value to calculate the heat of vaporization for methanol (m=Hvap/R)
