Plot a graph, similar to the one below, with the new variables

(1)/(T)

on the

x

-axis and

LnP

on the

y

-axis. Use the Microsoft Excel program to help you. If the original pressure versus temperature data for the unknown liquid conforms to the behavior predicted by the Claussius-Clapeyron Model, this plot should yield a straight line.\

(4.0*1)/(.9936)(-5472.1)k

\ The slope will yield a numerical value for:\

-(\\\\Delta Hv)/(R)

\ (K)\ The y-intercept will yield a numerical value for:

(\\\\Delta Hv)/(RT_(b))+LnP_(0),

(no units)\ The slope and y-intercept values can be extracted from the graphed data by using the "Trendline" function in the "Microsoft Excel" program. Using the known values for R and

P_(0)

, determine the values for

\\\\Delta H_(V)

and

T_(b)
