Abstract
The Burnett method was employed to study the volumetric behavior of fluoroform gas from 200 to 350[degrees]C at pressure up to 150 atmospheres. An estimate of the assignable measurement errors indicate the data should be accurate to 5 part in 10,000. A nonlinear regression analysis method was used to evaluate the second and the third virial coefficients of fluoroform gas. This data analysis method considers both the dependent and the independent variables are subject to error and eliminates the need for prior knowledge of the run constant and the apparatus constant to evaluate the second and the third virial coefficients of the gas. The parameters of Benedict- Webb-Rubin equation of state were evaluated by using the experimental Burnett p-v-T measurements. The Benedict- Webb-Rubin equation of state represents the data within the experimental error of the measurements.
