Nov 01, 2006 · Ne, and Xe). The results are useable in design, safety, environmental, and simulation applications. Correlation of vapor pressure The Antoine equation was selected for correlation of vapor pressure as a function of temperature: log10… Linear Regression Equation. The measure of the extent of the relationship between two variables is shown by the correlation coefficient. The range of this coefficient lies between -1 to +1. This coefficient shows the strength of the association of the observed data for two variables. A linear regression line equation is written in the form of:
The equation for molality is: m = mol solute/kg solvent. The Boiling-Point Elevation Equation The rather simple equation for determining boiling point of a solution: delta T = m K b .
The Antoine equation for calculating vapor pressure is given in Equation B.3, with the relevant constants in Table B.4. ln PVAP i ¼ Ai Bi T þ Ci (B.3) TABLE B.4 Antoine Equation Coefﬁcients for Selected Components Methanol Ethanol Benzene p-Xylene Toluene Chloroform Water Acetone A 8.07240 8.1122 6.90565 6.99052 6.95464 6.93710 8.01767 7.23160
