The value of Q₁₀, which describes the sensitivity of a reaction to temperature, is calculated as the A) rate of a process at a certain temperature, divided by its rate at 10°C. B) rate of a process at a certain temperature, divided by its rate at a temperature 10°C lower. C) rate of a process at a certain temperature, divided by its rate at a temperature 10°C higher. D) temperature at which the rate of a certain process doubles. E) temperature at which the rate of a certain process becomes insignificant.

Question

Quizplus · Accepted Answer

Q₁₀ is the activation energy, which is the energy required for a chemical reaction to occur. Q₁₀ is calculated as the ratio of the rate of a reaction at a certain temperature to the rate of the same reaction at a temperature 10°C lower. This is known as the Arrhenius equation. Therefore, choice B is the correct answer.
