Summary of Results from Runs 5 to 8
Run 5:
A plot of Log10 (vapor pressure (Pa)) versus reciprocal temperature (1/T(K)) for Run 5 gives the following statistical data using an unweighted least squares treatment.
Slope: -4.06 x 103
Standard error in slope: 220
Intercept: 10.8
Standard error in intercept: 0.693
The results obtained indicate the following vapor pressure relationship:
Log10 (Vp (Pa)) = -4.06 x 103/temp(K) + 10.8
The above yields a vapor pressure (Pa) at 298.15 K with a common logarithm of -2.82.
Run 6:
A plot of Log10 (vapor pressure (Pa)) versus reciprocal temperature (1/T(K)) for Run 6 gives the following statistical data using an unweighted least squares treatment.
Slope: -3.71 x 103
Standard error in slope: 223
Intercept: 9.64
Standard error in intercept: 0.700
The results obtained indicate the following vapor pressure relationship:
Log10 (Vp (Pa)) = -3.71 x 103/temp(K) + 9.64
The above yields a vapor pressure (Pa) at 298.15 K with a common logarithm of -2.79.
Run 7:
A plot of Log10 (vapor pressure (Pa)) versus reciprocal temperature (1/T(K)) for Run 7 gives the following statistical data using an unweighted least squares treatment.
Slope: -3.58 x 103
Standard error in slope: 406
Intercept: 9.18
Standard error in intercept: 1.28
The results obtained indicate the following vapor pressure relationship:
Log10 (Vp (Pa)) = -3.58 x 103/temp(K) + 9.18
The above yields a vapor pressure (Pa) at 298.15 K with a common logarithm of -2.83.
Run 8:
A plot of Log10 (vapor pressure (Pa)) versus reciprocal temperature (1/T(K)) for Run 8 gives the following statistical data using an unweighted least squares treatment.
Slope: -3.60 x 103
Standard error in slope: 464
Intercept: 9.24
Standard error in intercept: 1.46
The results obtained indicate the following vapor pressure relationship:
Log10 (Vp (Pa)) = -3.60 x 103/temp(K) + 9.24
The above yields a vapor pressure (Pa) at 298.15 K with a common logarithm of -2.84.
Summary of Results
The values of vapor pressure at 25 °C extrapolated from each graph are summarized in the following table:
