Answer to Question #276765 in Chemistry for michelle

Question

In a calorimetry experiment, if the temperature of the water decreases, then the reaction is? 

1. not enough information
2. endothermic
3. exothermic
4. energy neutral (ΔH=0)

Answer 1

Solution:

If an endothermic reaction runs, the heat required by the reaction is removed from the solution and the temperature of the solution decreases.

Thus, this reaction is endothermic

Answer: "2. endothermic"
