Graphically determine activation energy

WebUsing an Arrhenius plot: A graph of ln k against 1/T can be plotted, and then used to calculate E a. This gives a line which follows the form y = mx + c. The graph of ln k against 1/T is a straight line with gradient -Ea/R. From the graph, the equation in the form of y = mx + c is as follows: WebThe activation energy is shown as a 'hump' in the line, which: starts at the energy of the reactants; is equal to the difference in energy between the top of the 'hump' and the reactant;
