The temperature coefficient of a reaction is the factor by which its rate increases for every rise of:

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: Constant Half-Lifetime[A][A]₀[A]₀/22 × t½[A]₀/4Each successive half-life takes the SAME amount of time, regardless of starting concentration

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.
