Arrhenius Equation
Arrhenius equation is a mathematical expression to give a quantitative relationship between rate constant and temperature, and the expression is
where, A = frequency or Arrhenius factor. It is also called pre-exponential factor
R = gas constant
Ea = activation energy
Activated complex( or transition state)
Activated complex is the highest energy unstable intermediate between the reactants and products and gets decomposed immediately( having very short life), to give the products. In this state, bonds of reactant are not completely broken while the bonds of products are not completely formed.
