Answer 1

Answer:

Thermochemistry is the study of (a) heat changes accompanying chemical reaction.

Explanation:

Answer 2

The answer to the given question is as follow:

Thermochemistry is the study of heat changes accompanying chemical reactions.

• The study of heat energy associated with chemical reactions and/or phase changes such as melting and boiling is known as thermochemistry.
• A phase change can release or absorb energy, just as a reaction can.

Thus, answer to the given question will be option (a).
