Define the terms k and E a in the Arrhenius equation, ln 𝑘 = ln 𝐴 − !!"#

In the Arrhenius equation, the terms k and Ea represent the following:

1. k: This is the rate constant of the reaction. It quantifies the speed of a chemical reaction. The value of k is temperature-dependent and can change with different environmental conditions.

2. Ea: This stands for the activation energy of the reaction. It is the minimum amount of energy required for a reaction to occur. It is usually measured in Joules per mole (J/mol) or kilocalories per mole (kcal/mol). The higher the activation energy, the slower the chemical reaction.
