Question

which branch studies energy and reaction rates?
○ analytical
○ physical chemistry
○ biochemistry

Explanation:

• Analytical chemistry focuses on analyzing the composition of substances, not energy and reaction rates.
• Physical chemistry deals with the physical properties and processes of chemical systems, including energy changes and reaction rates (e.g., thermodynamics and kinetics).
• Biochemistry focuses on chemical processes in living organisms, not primarily on general energy and reaction rates of chemical systems.

Answer:

B. Physical Chemistry
