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).

Buffer - pH

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.
