You study the effect of temperature on the rate of two reactions and graph the natural logarithm of the rate constant for each reaction as a function of 1/T. How do the two graphs compare:
(a) If the activation energy of the second reaction is higher than the activation energy of the first reaction but the two reactions have the same frequency factor, and
(b) If the frequency factor of the second reaction is higher than the frequency factor of the first reaction but the two reactions have the same activation energy?
