Method/Apparatus/Procedure:
The apparatus was similar to that used by Ben Naim and Baer [1] and is described in [2]. The apparatus consists of a burette system for the gas, a mercury manometer and a solution vessel. The mole fraction of dissolved gas is estimated from the volume change at constant pressure of saturated gas in the burettes, and the mass of the solvent in the solution vessel determined by weighing.
Source and Purity of Materials:

Experimental Data
The authors fitted their data to the equation:
ln x1 = - 10.1836 + 1274.115 (T/K)+ 0.2581 ln (T/K)
They also obtained ΔH/kJ mol-1 = -9.95 and ΔS/J K-1 mol-1 = -70 for the transfer of one mole of ethene from the gas phase at 101.32 kPa to the hypothetical unit mole fraction solution.
