Which term refers to the study of the rates at which chemical reactions occur?

• A. Electrochemistry
• B. Chemical kinetics
• C. Thermodynamics
• D. Stoichiometry

Answer: (B)

Verified step by step guidance

1. Understand that the question is asking for the term that describes the study of how fast chemical reactions happen.
2. Recall that Electrochemistry deals with the relationship between electricity and chemical reactions, not reaction rates.
3. Recognize that Thermodynamics focuses on the energy changes and equilibrium states of reactions, rather than their speed.
4. Know that Stoichiometry involves the quantitative relationships between reactants and products in chemical reactions, but not the rate at which reactions proceed.
5. Identify that Chemical kinetics is the branch of chemistry that specifically studies the rates of chemical reactions and the factors affecting them.
