What is thermochemistry?
Q: What is thermochemistry?
A: Thermochemistry is the study of the energy and heat related to chemical reactions and physical transformations.
Q: What are some examples of physical transformations?
A: Examples of physical transformations include melting (when a solid becomes a liquid) and boiling (when a liquid becomes a liquid).
Q: How does thermochemistry help predict reactant and product quantities?
A: Thermochemists use data, including entropy determinations, to predict reactant and product quantities at all times during a given reaction.
Q: Are endothermic reactions favorable or unfavorable?
A: Endothermic reactions are unfavorable.
Q: Are exothermic reactions favorable or unfavorable?
A: Exothermic reactions are favorable.
Q: What concepts does thermochemistry combine?
A: Thermochemistry combines the concepts of thermodynamics with the idea of energy in the form of chemical bonds.
Q: What types of calculations do thermochemists make?
A: Thermochemists make calculations such as heat capacity, heat of combustion, heat of formation, enthalpy, entropy, free energy, and calories.
