The Arrhenius equation shows that a plot of 1/temperature against ln(reaction rate) is linear, with a gradient corresponding to the activation energy of a reaction. This activation energy calculator uses two points to determine activation energy (Ea).

Two interconverting species A and B have an equilibrium ratio that depends on their difference in energy and the temperature, according to the equation ΔG=RT*ln(k), where k is the equilibrium constant. This can be derived from the Arrhenius equation calculator (temp-rate dependence) for the forward and backward reactions.
