Gibbs energy
Consistent estimation of Gibbs energy using component contributions.
... Group contribution methods were relatively successful in estimating the thermodynamic parameters of ideal gases [16– 19], and later extended to liquid and solid phases [20]. Only in 1988 [21] was it brought to the world ...
