Answer: Both b and c are correct.
- A Increases linearly with T
- B Increases exponentially with T
- C Decreases with increasing Ea
- D Both b and c are correct
Correct answer: D. Both b and c are correct
Explanation: k increases exponentially with temperature and decreases as activation energy Ea increases.
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.
