Abstract	The statistical rate theory (SRT) approach is derived and applied to predict the evaporation conditions of an ethanol droplet. In this study, a series of experiments of ethanol droplet evaporation at steady state have been conducted in an evaporation chamber. A temperature discontinuity is found across the liquid-vapor interface at the centerline during steady-state evaporation. The interfacial liquid temperature, the interfacial vapor temperature, the radius of droplet, and the average evaporation flux are used to predict the vapor-phase pressure. The predicted pressure is found to agree with the measured value. It is suggested that the SRT approach can predict the experimental evaporation conditions. As a factor in the SRT approach, the droplet radii are evaluated numerically. It is found that the radius with less than the micron scale significantly affects the vapor-phase pressure.
