Run 1
A plot of Log (vapour pressure (Pa)) versus reciprocal temperature (1 / T (K)) gives the following statistical data using an unweighted least squares treatment:
Slope: -1890.218
Standard deviation in slope: 16.170
Intercept: 10.014
Standard deviation in intercept: 0.048
The results indicate the following relationship: Log (Vp (Pa)) = -1890.218 / temp (K) + 10.014
This yields a vapour pressure (Pa) at 298.15 K with a common logarithm of 3.674.
Run 2
A plot of Log (vapour pressure (Pa)) versus reciprocal temperature (1 / T (K)) gives the following statistical data using an unweighted least squares treatment:
Slope: -1813.476
Standard deviation in slope: 8.828
Intercept: 9.806
Standard deviation in intercept: 0.026
The results indicate the following relationship: Log (Vp (Pa)) = -1813.476 / temp (K) + 9.806
This yields a vapour pressure (Pa) at 298.15 K with a common logarithm of 3.273.
Run 3
A plot of Log (vapour pressure (Pa)) versus reciprocal temperature (1 / T (K)) gives the following statistical data using an unweighted least squares treatment:
Slope: -2088.029
Standard deviation in slope: 15.617
Intercept: 10.554
Standard deviation in intercept: 0.046
The results indicate the following relationship: Log (Vp (Pa)) = -2088.029 / temp (K) + 10.554
This yields a vapour pressure (Pa) at 298.15 K with a common logarithm of 3.551.
Run 4
A plot of Log (vapour pressure (Pa)) versus reciprocal temperature (1 / T (K)) gives the following statistical data using an unweighted least squares treatment:
Slope: -1582.976
Standard deviation in slope: 8.271
Intercept: 9.170
Standard deviation in intercept: 0.024
The results indicate the following relationship: Log (Vp (Pa)) = -1582.976 / temp (K) + 9.170
This yields a vapour pressure (Pa) at 298.15 K with a common logarithm of 3.861.
Run 5
A plot of Log (vapour pressure (Pa)) versus reciprocal temperature (1 / T (K)) gives the following statistical data using an unweighted least squares treatment:
Slope: -1913.444
Standard deviation in slope: 7.477
Intercept: 10.059
Standard deviation in intercept: 0.022
The results indicate the following relationship: Log (Vp (Pa)) = -1913.444 / temp (K) + 10.059
This yields a vapour pressure (Pa) at 298.15 K with a common logarithm of 3.641.
