Reference
Run 1
A plot of Log10(vapour pressure (Pa)) versus reciprocal temperature (1/T(K)) for Run 1 gives the following statistical data using an unweighted least squares treatment.
Slope: | -4.02 x 103 |
Standard error in slope: | 316 |
Intercept: | 8.09 |
Standard error in intercept: | 0.791 |
The results obtained indicate the following vapor pressure relationship:
Log10(Vp (Pa)) = -4.02 x 103/temp(K) + 8.09
The above yields a vapor pressure (Pa) at 298.15 K with a common logarithm of -5.40.
Run 2
A plot of Log10(vapor pressure (Pa)) versus reciprocal temperature (1/T(K)) for Run 2 gives the following statistical data using an unweighted least squares treatment.
Slope: | -4.38 x 103 |
Standard error in slope: | 372 |
Intercept: | 8.93 |
Standard error in intercept: | 0.931 |
The results obtained indicate the following vapor pressure relationship:
Log10(Vp (Pa)) = -4.38 x 103/temp(K) + 8.93
The above yields a vapor pressure (Pa) at 298.15 K with a common logarithm of -5.77.
Run 3
A plot of Log10(vapor pressure (Pa)) versus reciprocal temperature (1/T(K)) for Run 3 gives the following statistical data using an unweighted least squares treatment.
Slope: | -3.63 x 103 |
Standard error in slope: | 445 |
Intercept: | 7.05 |
Standard error in intercept: | 1.12 |
The results obtained indicate the following vapor pressure relationship:
Log10(Vp (Pa)) = -3.63 x 103/temp(K) + 7.05
The above yields a vapor pressure (Pa) at 298.15 K with a common logarithm of -5.14.
Run 4
A plot of Log10(vapor pressure (Pa)) versus reciprocal temperature (1/T(K)) for Run 4 gives the following statistical data using an unweighted least squares treatment.
Slope: | -4.56 x 103 |
Standard error in slope: | 464 |
Intercept: | 9.31 |
Standard error in intercept: | 1.16 |
The results obtained indicate the following vapor pressure relationship:
Log10 (Vp (Pa)) = -4.56 x 103/temp(K) + 9.31
The above yields a vapor pressure (Pa) at 298.15 K with a common logarithm of -5.97.
Summary of Results
The values of vapor pressure at 25 °C extrapolated from each graph are summarized in the following table:
Run | Log10[Vp(25 ºC)] |
1 | -5.40 |
2 | -5.77 |
3 | -5.14 |
4 | -5.97 |
Mean | -5.57 |
Vapor Pressure | 2.68 x 10-6 Pa |
