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 Arrhenius Constant for Second Order Reaction?
Arrhenius Constant for Second Order Reaction calculator uses Frequency Factor from Arrhenius Eqn for 2nd Order = Rate Constant for Second Order Reaction/exp(-Activation Energy/([R]*Temperature for Second Order Reaction)) to calculate the Frequency Factor from Arrhenius Eqn for 2nd Order, The Arrhenius constant for second order reaction formula is defined as rate constant of second order reaction per exponential form of negative activation energy divide by universal gas constant and temperature. The frequency factor measures the frequency of the molecular collisions that have the proper orientation between particles and appropriate temperature so that the reaction can occur. Frequency Factor from Arrhenius Eqn for 2nd Order is denoted by A_{factor-secondorder} symbol.
