jee-mainjee-advancedneet-ug
k = A e^{-Ea/(RT)}
What each symbol means
| Symbol | What it stands for |
|---|---|
| A | Pre-exponential factor (same units as k) |
| R | 8.314 J mol⁻¹ K⁻¹ |
| T | Absolute temperature (K) |
| k | Rate constant |
| E_a | Activation energy (J mol⁻¹, often kJ mol⁻¹) |
When to use this
Empirical relation linking k and T; thermodynamic T in kelvin only.
