50kJmol
The term 50 kJ mol⁻¹ is a molar energy quantity frequently encountered in physical chemistry and thermodynamics. It represents an energy of fifty kilojoules associated with one mole of entities, whether molecules, atoms, ions, or conjugated systems. Because it is a molar quantity, it is directly comparable to thermodynamic functions such as enthalpy (ΔH), free energy (ΔG), or activation energy (Eₐ) that are normally expressed per mole.
In numerical terms, 50 kJ mol⁻¹ equals 12 kcal mol⁻¹ (1 kcal = 4.184 kJ) and, on a per–molecule basis, approximately 0.52 eV (1 eV = 96.485 kJ mol⁻¹).
In kinetic studies, an activation energy of 50 kJ mol⁻¹ corresponds to a moderate temperature dependence, meaning the
Because the unit is dimensionless with respect to mole, it integrates seamlessly into equations of state, calorimetry,
