Thermochemistry Unit Review Packet

Welcome! This three-page resource targets core concepts and skills in a thermochemistry unit of high school chemistry or advanced second-year chemistry course. To complete this study guide, students will need to perform the following tasks.

• Calculate the mass, heat energy, specific heat capacity, or change in temperature of a substance using a specific heat equation
• Calculate the entropy, enthalpy, or Gibbs' free energy value using Gibb's free energy equation
• Identify the meaning and what the chemical symbols used in the core unit equations represent
• Match the chemical symbol (i.e., S, Q, m, etc.) with the appropriate units of measurement
• Predict whether a specific chemical reaction is endothermic or exothermic and defend your answer
• Predict whether increasing or decreasing an isolated variable in Gibb’s free energy equation will contribute towards a spontaneous reaction or a non-spontaneous reaction

I provided a full key with the answers in bold, red font. I showed the work for each of the dimensional analysis problems.

I included a segmented triangle on the top of page one for students who prefer using the triangle method for isolating the unknown variable.

I also included a definition word bank of the chemical symbols for the chemical symbol analysis table.

This study guide is a PDF file. You can use it as a test as well. First, convert this file to Microsoft Word document using an Adobe Acrobat Reader DC app. Then change the title and assign point values for the questions in each section.

I appreciate your interest. I have published science kits, games, books, and posters through several international science supply companies dating back to 2002. Order with confidence!
