1 – 7 of 7 Classroom Resources

• Equilibrium Constants, Le Châtelier's Principle, Gibb's Free Energy , Enthalpy, Entropy, Solubility | High School

### Access is an AACT member benefit. Lesson Plan: Relationship Between Free Energy and the Equilibrium Constant

In this lesson, students will explore the relationships between solubility and Keq (specifically Ksp), as well as Keq and ΔG°. First, a guided inquiry activity will introduce the relationship between standard free energy and equilibrium constant with the equation ΔG° = -RTlnKeq. Then data collection regarding solubility of potassium nitrate at various temperatures will lead to the calculation of Ksp and ΔGo for the dissolution reaction at those temperatures. Students will manipulate the equations ΔG° = -RTlnKeq and ΔG° = ΔH° - TΔS° to derive a linear relationship between 1/T and lnKeq, which will then be graphed to determine values for ΔH° and ΔS°.

• Enthalpy, Entropy, Gibb's Free Energy | High School

### Access is an AACT member benefit. Lab: Thermodynamics Escape Room

In this lab, students are presented with an escape room scenario that challenges them to complete three tasks in order to escape from an old, mysterious Gothic house. Students are given access to a small assortment of chemicals, and standard lab equipment. They must determine which chemicals and equipment will help them to light a tap light without touching it, free a key from a block of ice without using a conventional heat source, and free a lock that is buried in a pile of glue.

• Enthalpy, Entropy, Gibb's Free Energy , Spontaneous vs. Non-spontaneous Reactions, Exothermic & Endothermic | High School

### Access is an AACT member benefit. Lab: Investigating Enthalpy and Entropy

In this lab, students will be able to observe and measure energy changes during the formation of solutions. The students should be able to explain and describe these changes in terms of entropy, enthalpy and free energy.

• Heat, Temperature, Specific Heat, Exothermic & Endothermic, Energy Diagrams, Hess's Law, Calorimetry, Entropy, Enthalpy, Gibb's Free Energy | High School

### Lesson Plan: Thermochemistry and Thermodynamics Unit Plan

The AACT high school classroom resource library and multimedia collection has everything you need to put together a unit plan for your classroom: lessons, activities, labs, projects, videos, simulations, and animations. We constructed a unit plan using AACT resources that is designed to teach thermochemistry and thermodynamics to your students.

• Electrolytic Cells, Galvanic Cells, Electrolysis, Redox Reaction, Gibb's Free Energy | High School

### Access is an AACT member benefit. Lesson Plan: Exploration of Electrolytic Cells

In this lesson, students will build several electrolytic cells, discuss and diagram their cells to further their understanding of electrolysis, and use qualitative and quantitative analysis of the electrolysis of potassium iodide. Finally, students will practice and be assessed on their knowledge of electrolysis on AP exam-level questioning.

• Entropy, Gibb's Free Energy , Enthalpy | High School

### Access is an AACT member benefit. Lesson Plan: Enthalpy and Entropy as Driving Forces

In this activity, students observe various chemical and physical processes to qualitatively predict and explain the signs of ∆S and ∆H. Based on their observations, they will predict the sign of ∆G and will determine the driving force of the process. Students will then calculate ∆S, ∆H and ∆G. This lesson focuses on thermochemical predictions, calculations and explanations.

• Redox Reaction, Gibb's Free Energy , Spontaneous Reactions , Reduction, Oxidation, Half Reactions, Galvanic Cells, Electrons, Electron Transfer, Cathode, Anode, Reduction Potentials, Exothermic & Endothermic, Spontaneous vs. Non-spontaneous Reactions, Spontaneous Reactions, Dimensional Analysis | High School

### Access is an AACT member benefit. Lesson Plan: How Far Can We Go?

In this lesson students compare energy densities of lead acid and lithium ion batteries to understand the relationship between electrochemical cell potentials and utilization of stored chemical energy.
