intrinsic barrier
The Gibbs @[email protected] (\(\Delta ^{\ddagger}G\)) in the limiting case where \(\Delta G^{\,\unicode{x26ac}} = 0\), i.e. when the effect of thermodynamic driving force is eliminated. According to the @[email protected], the intrinsic barrier is related to the @[email protected], \(\lambda \), of the reaction by the equation: \[\Delta ^{\ddagger}G = \frac{\lambda }{4}\]
