Answer: chemical kinetics.
- A thermodynamics
- B chemical kinetics
- C electrochemistry
- D stoichiometry
Correct answer: B. chemical kinetics
Explanation: Chemical kinetics studies how fast reactions occur and the factors affecting them.
First-order decay curve: concentration halves every t½, and that half-life is constant - a defining test for first-order kinetics.
Concept context
Study the speed of reactions and what affects it: concentration, temperature, and catalysts. Covers rate law, order of reaction, the Arrhenius equation, and reaction mechanisms step by step.
