Answer: log k vs 1/T.
- A Rate vs concentration
- B log k vs 1/T
- C k vs T
- D Rate vs time
Correct answer: B. log k vs 1/T
Explanation: From Arrhenius: log k = log A - Ea/(2.303RT). Slope of log k vs 1/T equals -Ea/(2.303R).
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.
