NCERT · Class 12 · Chemistry · Chemical KineticsAccording to the Arrhenius equation, the rate constant $k$ is expressed as:
Step-by-Step Solution
The Arrhenius equation is given by $k = A e^{-E_a / RT}$, where $A$ is the Arrhenius factor (frequency factor), $E_a$ is activation energy, $R$ is gas constant, and $T$ is temperature.
