hi! how do you do the last part regarding slope and hvap?
![The enthalpy of vaporization (AHvap) is determined from the Clausius-Clapeyron equation:
In VP = (-AHvap/R)(1/T) +C (Note: the form of this equation is linear: y = mx + b)
Use a Google Sheets to calculate the values for the x and y axis from the data given below and to
plot the natural log of vapor pressure (In VP) versus the inverse temperature in Kelvin (1/T).
Trial # T(K)
VP(mmHg)

298.2
116.2

Paste the data table into your spreadsheet so that Trial # is in cell A1.
A new column is inserted on the spreadsheet between the T(K) and VP(mmHg) columns for the 1/T
calculation.
• What formula to calculate 1/T is typed into the cell directly to the right of 298.2 (cell C2)?
=1/B2
• How is the calculation completed for Trials 2-6? both of these
In column E, calculate In VP.
• What formula to calculate In VP is typed into the cell directly to the right of 116.2 (cell E2)?
=In(D2)
• How is the calculation completed for Trials 2-6? both of these
Plot column C vs column E.
• After highlighting both columns, what is the next step?
