Q.Write Arrhenius equation and explain the terms involved.

Step 1. The Arrhenius equation is $k=Ae^{-E_a/RT}$.

Step 2. k is the rate constant of the reaction at temperature T.

Step 3. A is the frequency factor (or pre-exponential factor), related to the frequency of collisions between reactant molecules; it is treated as approximately constant over ordinary temperature ranges.

Step 4. $E_a$ is the activation energy -- the minimum energy the colliding molecules must together possess for the reaction to occur.

Step 5. R is the universal gas constant ($8.314\ \text{J K}^{-1}\text{mol}^{-1}$), and T is the absolute temperature in kelvin. …

State the Arrhenius equation and define each of its four symbols (k, A, $E_a$, T with R as the univers …
