Which of the following would increase the rate of the following reaction?
C₂H₄ (g) + O₃ (g) →C₂H₄O (g) + O₂ (g)
I. Add more O₃ to this reaction.
II. Decrease the temperature.
III. Add a catalyst.

Question

Quizplus · Accepted Answer

Adding more of the reactant O₃ will increase its concentration, which will increase the frequency of collisions between molecules and increase the reaction rate. Adding a catalyst will also increase the rate of the reaction by providing an alternate reaction pathway with a lower activation energy. Decreasing the temperature will actually decrease the rate of the reaction, as it will result in fewer successful collisions between molecules due to a decrease in kinetic energy.
