### Lesson Plan: AP Chemistry Experimental Evidence Review

In this lesson, students will evaluate data from 16 simulated lab experiments that were designed to mirror the Recommended Labs from the College Board. Corresponding lab experiments and demonstration options have also been included for teacher reference.

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

### 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 DG°. First, a guided inquiry activity will introduce the relationship between standard free energy and equilibrium constant with the equation DG° = -RTlnKeq. Then data collection regarding solubility of potassium nitrate at various temperatures will lead to the calculation of Ksp and DGo for the dissolution reaction at those temperatures. Students will manipulate the equations DG° = -RTlnKeq and DG° = DH° - TDS° to derive a linear relationship between 1/T and lnKeq, which will then be graphed to determine values for DH° and DS°.

• Calorimetry, Heat, Hess's Law, Enthalpy, Error Analysis | High School

### Lab: Utilizing Hess's Law

In this lab, students will use a coffee cup calorimeter to collect data that will allow them to calculate ∆H for two reactions. The first reaction, between sodium bicarbonate and hydrochloric acid is endothermic. The second, between sodium carbonate and hydrochloric pressure, is exothermic. They will then use their experimental values and Hess’s Law to determine ∆H for the decomposition of sodium bicarbonate, compare their calculated value to the theoretical value, and calculate the percent error. This resource includes a prelab presentation and sample calculations.

### 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.

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

### 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.

### 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.

• Catalysts, Entropy, Equilibrium Constants, Enthalpy, Activation Energy, Energy Diagrams, Reaction Quotient, Spontaneous vs. Non-spontaneous Reactions | High School

### Lesson Plan: Making Connections in Kinetics, Equilibrium and Thermochemistry

Additionally students will be able to determine if a reaction is kinetically favored or thermodynamically favored.

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

### 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.

### Lab: Less Than Zero

In this lab, students will investigate the endothermic reaction between baking soda and HCl. Students will consider stoichiometric ratios, molar concentrations, reaction scale, and calorimetry. The lab starts with a scripted reaction that uses given molar ratios, a glass beaker, and 2-M HCl. They will witness a temperature drop of about 5 to 8 C. Students then adjust the experiment so they can achieve a temperature drop of more than 20 C.
