Reaction rate constant (By the Arrhenius equation)
Formula
k
the rate constant at temperature T
A
the pre-exponential factor or simply the prefactor
Ea
the activation energy of the reaction
T
the temperature
Formula description
The Arrhenius equation gives the dependence of the rate constant k of chemical reactions on the temperature and activation energy.

k = A*exp(-Ea/8.314462175/T)
k = A*Math.Exp(-Ea/8.314462175/T)
#include
k = A*exp(-Ea/8.314462175/T)
k = A*Math.exp(-Ea/8.314462175/T)
k = A*Math.exp(-Ea/8.314462175/T)
k=A e^{-E_a/R T}
$k = $A*exp(-$Ea/8.314462175/$T)
