____ is the branch of chemistry that would measure the energy changes in chemical reactions.
A
Energetics
B
Organic Chemistry
C
Biochemistry
D
Kinetics
Explanation: 

Detailed explanation-1: -Thermochemistry is defined as the branch of thermodynamics that focuses on changes occurring during chemical reactions.

Detailed explanation-2: -The study of chemical energetics deals with the energy changes during a chemical reaction. During chemical reactions, energy is either released or absorbed. Chemical energetics tells us whether a chemical reaction can take place spontaneously or not and about the feasibility of a reaction.

Detailed explanation-3: -All chemical reactions exchange energy with the surroundings by releasing or absorbing heat. Reactions that produce or consume gases also exchange energy as pressure-volume work. If a chemical reaction releases heat, it is exothermic. If a chemical reaction absorbs heat, it is endothermic.
