In order to design an experiment to model exothermic reactions, a student places various levels of calcium chloride (0 grams, 2 grams, 4 grams, 6 grams, 8 grams, and 10 grams) into beakers with 100 ml of water. The temperature of the water taken before and after the calcium chloride is placed in the solution is recorded. What evidence would support the student's claim that the concentration of calcium chloride is directly related to the amount of energy in the reaction?

The concentration of the calcium chloride is directly related to the amount of energy because as the concentration of chloride is raised the temperature of the water will rise more dramatically and probably more rapidly, that means the reaction will hit higher temperatures in a short period of time.

Going by the experimental setup, the evidence that would support the claim that the concentration of calcium chloride is directly related to the amount of energy in the reaction is if the temperature change in the beakers varies with the amount of calcium chloride placed in them.

The dissolution of calcium chloride in water is an energy-releasing (exothermic) reaction. Thus, the final temperature of each beaker containing a certain level of the chemical is expected to be more than the initial temperature.

If the temperature change increases in relation to increasing amounts of calcium chloride in each beaker, then, this will support the claim of the student that the concentration of calcium chloride is directly related to the amount of energy in the reaction.
