The pKa of a substance is a logarithmic scale that relates its dissocation constant to give acid in aqueous solution. Low (i.e. negative) numbers relate to strong acids. Together with the total substance concentration it allows an approximate pH to be calculated.

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).

Arrhenius equation

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.
