Can someone please provide me with the value of Gibbs free energy of formation (Delta G sub f sup o), for the chemical 2, 4-D (2, 4-dichlorophenoxyacetic acid) - C8H6Cl2O3.
Alternatively, (Delta G sup o), or (K sub eq) of reaction(s) in which 2, 4-D is formed and for which (Delta G sub f sup o) of all other components are known.
Please can you give references; or if it comes from your own work, I will cite you as the information source.
Many thanks.
