Consider the version of the Arrhenius equation that uses the natural log of the ratio of the rate constants. This ratio of the rate constants is directly proportional to which of the following?
A. Activation energy
B. Preexponential factor
C. Ideal gas constant
D. Change in temperature
A
The desired version of the Arrhenius equation is given by the following expression.
The term on the left is inversely proportional to the ideal gas constant. The term on the left is directly proportional to the change in inverse temperature but not in temperature. The preexponential factor does not even appear in the above expression. The activation energy, is directly proportional to the natural log of the ratio of the rate constants.
