## intrinsic barrier

https://doi.org/10.1351/goldbook.I03135
The Gibbs @E02108@ ($$\Delta ^{\ddagger}G$$) in the limiting case where $$\Delta G^{\,\unicode{x26ac}} = 0$$, i.e. when the effect of thermodynamic driving force is eliminated. According to the @M03702@, the intrinsic barrier is related to the @R05292@, $$\lambda$$, of the reaction by the equation: $\Delta ^{\ddagger}G = \frac{\lambda }{4}$
