A group of students investigated how temperature affects the rate of chemical reactions. They used hydrogen peroxide, which breaks down into oxygen and water, for their experiment. The students measured how long it took to obtain 50 mL of oxygen gas from a given volume of hydrogen peroxide heated to different temperatures. Their data are shown in the table below. Temperature (°C) Time (minutes) 10 33 20 16 30 8 40 4 50 2 Based on the students' data, select the correct conclusion about the rate of chemical reactions. A. Reaction rates increase as time increases. B. Reaction rates decrease as time decreases. C. Reaction rates increase as temperature increases. D. Reaction rates decrease as temperature increases.

ANSWER:
D. Reaction rates decrease as temperature increases.
EXPLANATION:
Catalase functions best at around 37 degrees Celsius -- as the temperature gets warmer or cooler than that, its ability to function will decrease.
pls correct me if I'm wrong <3
