# Chemistry: Thermal Chemistry and Thermodynamics

We have 15 ready-to-use problem sets on the topic of thermal chemistry and thermodynamics. These problem sets will focus on the use of thermodynamic concepts and equations to solve problems and mathematically analyze situations pertaining to chemical reactions and energy changes. Problems will range from the very easy plug-and-chug to the more difficult analysis of multi-step problems.
