Document Summary

Historical perspectives on van der waals attractive forces. 1873 - j. d. van der waals (danish physicist) ) = nrt [1] where a/v2 accounts for the attractive forces between molecules, b accounts for the finite volume of the molecules, and n is the number of moles of gas in a volume, v, at a temperature, t, and pressure, p. For a variety of gases, the coefficients have been determined for the van der. 0. 04278 van der waals corrections applied to a variety of common gases. Based on 1 mole of gas at a constant volume of 22. 4 liters. Note the deviation at low temperature for the acetic acid relative to these other gases. This indicates that acetic acid molecules are attracted toward one another. Depending on the units used, the universal gas constant, r, can take on variety of values including. R gm lb gm lb gm lb gm lb gm lb gm lb.
