What is the Eyring equation?

The Eyring equation is used to calculate the rate of a chemical reaction at different temperatures. It is written as k = (k_b[t])/h) * e^(-delta.G/Rt).

In the Eyring equation, "k" equals the reaction rate constant, "t" equals the temperature, "k_b" equals the Boltzmann constant, "h" equals Planck's constant, "delta G" is the Gibbs energy of activation and "R" is the gas constant. The formula can also be rewritten in terms of either the enthalpy of activation or the entropy of activation. Without a specific value for "k," the equation can also be used to find the ratios of the constants in regards to different temperatures for a reaction. The Eyring equation is similar to the Arrhenius equation.
