Answer: 10 °C.
- A 1 °C
- B 10 °C
- C 100 °C
- D 273 °C
Correct answer: B. 10 °C
Explanation: The temperature coefficient is the ratio of rate constants for a 10 °C (10 K) rise, usually about 2–3.
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.
