The Arrhenius equation can be reformulated in a way that permits the experimental determination of activation energies. For this purpose, we take the natural logarithm of both sides and convert into the base 10 logarithm.

The rate constant k is measured at several temperatures T and a plot of log k versus 1 /T is prepared, a straight line. What is the slope of this line? What is its intercept (i.e., the value of log it at 1/T = 0)? How is E., calculated?
