Arrhenius diagram

Arrhenius diagram (also know as Arrhenius plot): Graph that shows the logarithmic rate of heat reaction ln(q) versus the inverse temperature (1/T) in Kelvin. This results in a straight line with a gradient -Ea/R. In practice, the rate of reaction is often affected by physical processes (e.g. diffusion or mass transfer), which results in the occurrence of an apparent activation energy.
