The Eyring Equation is a mathematical expression derived from TST that relates the reaction rate to the temperature and activation energy. It provides a quantitative way to predict reaction rates and understand the effect of temperature and catalyst on these rates. The equation is:
\[ k = \frac{k_B T}{h} e^{-\Delta G^\ddagger / RT} \]
where \( k \) is the rate constant, \( k_B \) is the Boltzmann constant, \( T \) is the temperature, \( h \) is the Planck constant, and \( \Delta G^\ddagger \) is the Gibbs free energy of activation.
