Now we can make good use of the fact that zero- first- and second-order data can be plotted in different ways, and the correct model should yield a linear graph. To use this online calculator for Activation energy for second order reaction, enter Temperature (T), Frequency factor from Arrhenius equation (A) and Rate constant for second order reaction (k) and hit the calculate button. 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. The rate constant for this second-order reaction is 50.4 L/mol/h. Second order reactions can be defined as chemical reactions wherein the sum of the exponents in the corresponding rate law of the chemical reaction is equal to two. The rate constant for this second-order reaction is 8.0 × 10 −8 L/mol/s. Second order reactions. Initial conditions are also supported. The second reactant has no impact on rate and is of the zeroth order. Next, determine the order of reactions.

Arrhenius showed that the rate constant (velocity constant) of a reaction increases exponentially with an increase in temperature. The value of n is not related to the reaction stoichiometry and must be determined by experiment. The feed, which is equal molar in water (which contains the catalyst) and A, enters the reactor at a temperature of 52˚C and a total volumetric flow rate of 10 dm 3 /min. is carried out adiabatically in a CSTR.
