Kissinger equation is widely used to calculate the activation energy. In its derivation, a number of assumptions and estimates are introduced, and thus the activation energy calculated by Kissinger equation exists theoretical error. An evaluating method of model-free Kissinger equation is put forward....
[43]. From this we calculate the vector ∇Er as the first-order partial derivatives of the model with respect to A and B, which is given by (11)∇Er=(exp(−B/T),Aexp(−B/T)T)T. Evaluating at the nominal values for the parameters β0, we calculate the information matrix ...

Using the Arrhenius equation: ln k2/k1 = Ea/R(1/t1 - 1/t2) this equation allows you to calculate a new rate constant as the temperature changes. We know the rate of reaction will vary with temperature and thus so will the K values K are are rate constants, Ea is the activation en...
The Michaelis-Menten equation calculator allows you to discover the kinetics of one-substrate reaction catalyzed with an enzyme. Michaelis-Menten kinetics allows you to calculate the rate of the reaction, V, substrate concentration, Km, and the maximum rate of reaction, Vmax. In the article below...
The Nernst equation is frequently used to calculate the cell potential of an electrochemical cell at any temperature, pressure, or reactant concentration. Walther Hermann Nernst, a German scientist, first proposed the equation. Definition:The relationship between cell potential and standard potential, as...
However, on short T ranges you may get a straight line, and can thus calculate the activation energy Ea. Activation energy is always negative, meaning one has to add it to the reactants for them to start the reaction. A general explanation of why higher temperatures increase the rates of...
