In a certain chemical reaction, Reactant 1 and Reactant 2 release thermal energy. Students collect data by measuring the temperature change produced by adding increasing amounts of Reactant 2 to 25 grams of Reactant 1. They graph the data. Students must design a device that uses 25 grams of Reactant 1 and produces the maximum amount of heat with the smallest amount of Reactant 2. How much of Reactant 2 should they use to meet the criteria of the design challenge?

• 10 grams

• 15 grams

• 20 grams

• 25 grams
