Solution

Correct Answer:

k = Ae⁻ᵉᵃᵎᴿᵀ⁾

The Arrhenius Equation quantifies the effect of temperature on the rate constant :

  • : Rate constant
  • : Pre-exponential factor or Frequency factor
  • : Activation energy (minimum energy for a successful collision)
  • : Universal gas constant
  • : Absolute temperature (Kelvin)
  • The term represents the fraction of molecules that have energy greater than the activation energy.

This easy difficulty chemistry question is from the chapter chemical kinetics, covering the topic of arrhenius equation. It appeared in the 2025 exam.
