A modified Redlich-Kwong equation of state is proposed. Vapor pressures of pure compounds can be closely reproduced by assuming the parameter a in the original equation to be temperature-dependent. With the introduction of the acentric factor as a third parameter, a generalized correlation for the m
## Abstract A modified RedlichโKwong equation of state is developed in which the two parameters are expressed as functions of temperature. The critical values for the two constants in the equation are completely determined by the values of the critical properties of the gas. The optimum values of t
Ah&act-A modified Redlich-Kwong equation of state is given for accurately representing the volumetric properties of non-polar hydrocarbons. It is presented under a generalized corresponding states form which permits the prediction of pure component properties from the critical properties and acentri
