A plot of Log10(vapour pressure (Pa)) versus reciprocal temperature (l/T(K)) for Run 1 gives the following statistical data using an unweighted least squares treatment.
Slope = -2148.673
Standard deviation in slope: 94.129
Intercept: 6.058
Standard deviation in intercept: 0.304
The results obtained indicate the following vapour pressure relationship:
LoglO(Vp (Pa))=-2148.673/temp(K)+6.058.
The above yields a vapour pressure (Pa) at 298.15 K with a common logarithm of -1.149.
