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.

The units for the Arrhenius constant and the rate constant are the same, and depend on the rate of reaction. The units for corresponding orders are in the brackets: order zero (M * s-1), one (s-1), two (M-1 * s-1), ..., up to order n (M1-n * s-1).

Activation energy

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).


The molar concentration or number of molecules per unit volume (choose as desired from the menu) is calculated from the mass concentration by use of the molecular weight and object density.
