what is delta g units?
Chemists normally measure energy (both enthalpy and Gibbs free energy) in kJ mol-1 (kilojoules per mole) but measure entropy in J K‑1 mol-1 (joules per kelvin per mole). So it is necessary to convert the units – usually by dividing the entropy values by 1000 so that they are measured in kJ K‑1 mol-1.
