A group of student investigated how temperature affects the rate of chemical reactions. They used hydrogen peroxide, which breaks down into oxygen and water, for the investigation. The students measured how long it too to obtain 50 mL of oxygen gas from a given volume of hydrogen peroxide heated to different temperatures. Examine their data shown in the table below. Based on the students' data, select the correct conclusion about the rate of this chemical reaction.

• Reaction rates increase as time increases.

• Reaction rates decrease as time decreases.

• Reaction rates decrease as temperature increases

• Reaction rates increase as temperature increases.
