Excess enthalpies in the gas phase for the ethylene‐carbon dioxide system have been measured by a continuous‐flow isothermal calorimeter. Excess enthalpies are presented for mol fractions ranging from approximately 0.15 to 0.85, at three temperatures: 298.15, 318.15 and 338.15 K. For each isotherm, measurements were made at four pressures: 1.036 MPa (150 psia), 2.072 MPa (300 psia), 3.454 (500 psia) and 4.835 MPa (700 psia). The experimental results are compared with predictions using the Benedict‐Webb‐Rubin and Redlich‐Kwong equations of state.
