Detailed explanation-1: -Thermochemistry is basically a part of thermodynamics that focuses on heat absorbed or released during a chemical reaction.

Detailed explanation-2: -Thermochemistry is the branch of concerned with heat changes of chemical reactions.

Detailed explanation-3: -Thermochemistry is a branch of chemistry that qualitatively and quantitatively describes the energy changes that occur during chemical reactions. Energy is the capacity to do work.

Detailed explanation-4: -Chemical thermodynamics deals with the relationship between heat and other forms of chemical energy, kinetics with chemical reaction rates. Subdisciplines of physical chemistry include electrochemistry, photochemistry (see photochemical reaction), surface chemistry, and catalysis.

Detailed explanation-5: -This chapter focuses on thermochemistry, which is the study of the thermal energy associated with chemical and physical changes of substances.
