The rate constant of a chemical reaction was measured at several temperature values and a plot of ln k (on the y-axis) was plotted against 1/T (on the x-axis, temperature was measured in Kelvin).

If the slope of the plot was -13.38 x 103 K and the y-intercept was 18.0, what is the activation energy (EA) of the reaction in kJ mol-1?
