If the rate of a chemical reaction becomes slower at a given temperature, then the__________________?
Correct answer: D. Free energy of activation is higher
- A. Initial concentration of the reactants remains constant
- B. Free energy of activation is lower
- C. Entropy changes
- D. Free energy of activation is higher
Explanation
At a fixed temperature, a larger free energy of activation produces a smaller rate constant through the Arrhenius or Eyring relationship. The reaction consequently becomes slower.
