← ScienceWhich outcome affecting the manganese dioxide occurs when temperature is reduced, impacting reaction rate?
A)Lower MnO₂ catalytic activity exhibited✓
B)Increased MnO₂ surface area created
C)Slower MnO₂ particle decomposition starts
D)Decreased MnO₂ oxidation state change
💡 Explanation
Decreasing the temperature reduces the frequency of effective collisions, decreasing turnover frequency according to the Arrhenius equation, therefore manganese dioxide shows lower catalytic activity, rather than changes the other options because changes in those are independent of the temperature.
