Question 24

A student mixes two solutions in an insulated cup. The solutions react, and the student measures the temperature of the mixture.

MeasurementTemperature
Starting temperature20.0 ∘C20.0\ ^\circ\text{C}20.0 ∘C
Highest temperature reached27.5 ∘C27.5\ ^\circ\text{C}27.5 ∘C

Using the data, explain what happens to energy during the reaction and how the energy of the products compares with the energy of the reactants.
