What is significance of Arrhenius equation?
The Arrhenius equation explains the effect of temperature on the rate constant. There is certainly the minimum amount of energy known as threshold energy which the reactant molecule must possess before it can react to produce products. Most of the molecules of the reactants, however, have much less kinetic energy than the threshold energy at room temperature, and hence, they do not react. As the temperature is increased, the energy of the reactant molecules increases and become equal to or greater than the threshold energy, which causes the occurrence of reaction.
How to Calculate Activation Energy for Second Order Reaction?
Activation Energy for Second Order Reaction calculator uses Energy of Activation = [R]*Temperature_Kinetics*(ln(Frequency Factor from Arrhenius Equation)-ln(Rate Constant for Second Order Reaction)) to calculate the Energy of Activation, The Activation energy for second order reaction formula is defined as the multiplication of universal gas constant with temperature and with the difference of natural logarithms of frequency factor and rate constant. The minimum amount of energy that is required to activate atoms or molecules to a condition in which they can undergo chemical transformation is called activation energy. Energy of Activation is denoted by Ea symbol.
