Pseudo-second order kinetic
WebMar 21, 2024 · The pseudo-second-order (PSO) kinetic model has been popularly applied in the field of adsorption. The use of the nonlinear optimization method to obtain the parameters of the PSO model can minimize error functions during modelling compared to the linear method. WebA Second-Order Reaction is described mathematically as: 1/ [A] t = 1/ [A] t=0 + ν A kt For a Pseudo-Second-Order Reaction, the reaction rate constant k is replaced by the apparent reaction rate constant k'. If the reaction is not written out specifically to show a value of ν A, the value is assumed to be 1 and is not shown in these equations.
