Question: 66
6. What would increasing the concentration of reactants accomplish in a solution containing a saturated catalyst?
- A. It would increase the rate constant but not the reaction rate.
- B. It would decrease the rate constant but increase the reaction rate.
- C. It would increase the rate constant and increase the reaction rate.
- D. The reaction rate would be unaffected.
Correct Answer: D
Explanation:
While increasing the concentration of reactants can alter the reaction rate in first--or higher-order reactions, saturated solutions containing a catalyst have a maximum turnover rate that cannot adjust the rate constant or the reaction rate any higher.
