Introduction & Goals
Chemistry & Background
In Your Write-up
Your goal for this week is to identify chemical compounds which could be used to produce a chemical "cold pack" and a chemical "hot pack" to treat sports injuries. In this experiment you will determine the heats of reaction for an exothermic and an endothermic reaction in solution and learn what factors contribute to the spontaneity of the two reactions under study.
1. What happens to the temperature of the solution for exo- and endothermic reactions?
2. How is entropy changing in a dissolution reaction? What is the sign of S?
3. How do enthalpy and entropy contribute to G for each reaction?
4. How does thermodynamics relate to equilibrium? Is my reaction at equilibrium?
