The Arrhenius Equation quantifies the effect of temperature on the rate constant $k$: $k=A{e}^{-E_a/RT}$

• $k$: Rate constant
• $A$: Pre-exponential factor or Frequency factor
• $E_a$: Activation energy (minimum energy for a successful collision)
• $R$: Universal gas constant
• $T$: Absolute temperature (Kelvin)
• The term $e^{-E_a/RT}$ represents the fraction of molecules that have energy greater than the activation energy.
