Question
The temperature-dependence of the rate constants of a series of six related reactions are studied, and the reactions are all found to have the same rate constant at 370 K (their isokinetic temperature). Which statement best describes the relationship between the reactions’ Arrhenius pre-factors A and their activation energies Ea?
A.
The reactions share a common pre-factor A but differ in their activation energies Ea.
B.
The reactions share a common activation energy Ea but differ in their pre-factors A.
C.✓ Correct
As the reactions’ pre-factors A increase, their activation energies Ea increase.
D.
As the reactions’ pre-factors A increase, their activation energies Ea decrease.
