Thermochemistry
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.
Problem Sets
Set TC1: Specific Heat Capacity
5 Problems - Easy Difficulty
Relate the specific heat capacity of a material to the amount of heat absorbed or released to the temperature change and the mass of the sample.
Set TC2: Calorimetry 1
6 Problems - Easy Difficulty
Use the Q = m•C•∆T equation to analyze situations in which a heat transfer causes a temperature change.
Set TC3: Calorimetry 2
5 Problems - Medium Difficulty
Use the Q = m•C•∆T equation to analyze situations in which a heat transfer causes a temperature change.
Set TC4: Heat of Reaction 1
6 Problems - Medium Difficulty
