The activation energy for the reaction can be determined by finding the slope of the line. -Ea/R = slope. Ea = -R•slope. Which R? well what is the unit for Ea ...
In order to calculate the activation energy we need an equation that relates the rate constant of a reaction with the temperature (energy) of the system.
