Answer: 2.
- A 1
- B 2
- C 4
- D 10
Correct answer: B. 2
Explanation: A doubling of rate for a 10 K rise corresponds to a temperature coefficient of roughly 2.
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.
