Table (4.2) compiles the values of activation energy, frequency factor and<br />

order of reaction. The values of activation energy and frequency factor<br />

decrease as the amount of amino acid doping increases. The activation<br />

energy is considered as a barrier to be surmounted for reactant to combine to<br />
