Pseudo First Order – There are many types of vaccination procedures that we come across often. Some of them help speed up the reaction, while others can interfere with the results of any of the vaccination procedures. The sequence of reactions can be defined as the ratio of the energy to the concentrations of the reactants. In terms of the price rules shown, this is called the reaction sequence. Responses can have different orders, such as first order, second order, Pseudo First Order, etc. The course of the reaction depends on the concentration of the reactants. Let’s learn in detail the differences between vaccination procedures.

Suppose we have the following reaction: aij bB leads to cC+dD.

So according to the ratio rule = k AAx BBy

where x and y mean the concentrations of A and B.

The vaccine can be written as = x+y

We can also say that x is the order of the response for A and y is the order of the reactions for B.

Suppose the reaction with x = 1 and y = 1 is quadratic. If you know that the concentration of B is higher than that of A, then there will be a change in the concentration of B. It can be seen that in these cases the reaction procedure is important. Pseudo First Order for A. In this case, it is the pseudo-first vaccine.

Thus, even if the Pseudo First Order response is a higher response, this response will be estimated or presented as a first pseudo-first response. Thus, the pseudo-order response is similar to the order response but can be predicted or interpreted as the response of a certain order.

Pseudo First Order Reaction

It is defined as a non-first-line reaction but can occur first because there is a higher reactant level compared to other similar reactants or also called Pseudo First Order reaction.
for example

Let’s try to understand the Pseudo First Order using the examples below.

1. Hydration of the alkyl halide

CH3I H2O CH3OH H I = reaction rate calculated according to k [CH3I] [H2O]

During this reaction, methyl iodide is used so that an aqueous solution is formed to increase the water concentration higher than that of methyl iodide.

[CH3I] <<< [H2O]

In this case, it is assumed that the water concentration does not change much, or constantly, or changes rarely.

In this case, the vaccine value can be rewritten as = k ‘[CH3I]

where k ‘= k [H2O]

So we can say that the reaction appears to be first order, but in fact, it is second order. Hence, it is called a Pseudo First Order vaccine.

1. Hydrolysis of sugar cane

C12H22O11 H2O C6H12O6 C6H12O6

sucrose glucose fructose

Given the reaction rate = k [C12H22O11] [H2O]

But here, the water concentration is expressed as [H2O] >>> [C12H22O11].

Therefore, it can be estimated that the water concentration is constant, so it is assumed that there is no change in the water concentration.

The cost of the vaccine can be re-registered

r = k ‘[C12H22O11]

where k ‘= k [H2O]

In this case, the hydrolysis of the sugar is called Pseudo First Order.

1. Hydrolysis of esters
Reaction – CH3COOC2H5 H2O CH3COOH C2H5OH

= k [CH3COOC2H5] Reaction rate defined as [H2O]

Even then, the water concentration is considered higher. [H2O] >>> [CH3COOC2H5]

We assume that the water concentration remains almost constant throughout the reaction and can be recovered.

Reaction rate = k ‘[CH3COOC2H5]

K = k [H2O]

Although in this case the hydrolysis of the ester can be considered a Pseudo First Order reaction.

What is the difference between Pseudo first Order and Second Order Reaction?

I don’t think the second major is difficult, assuming you’ve already studied physical chemistry while in school. But for the pseudo-primary, rx always has more than one order but behaves as if it were first cut rx. The term “physician” is used several times in the literature to simplify the problems associated with bimolecular x-ray. (A B-> P) by the higher concentration of the other reagent B (for example).

Therefore, conc. The B’s do not seem to change over time, which can be considered constant. The advantage is that this can simplify our task since the speed rx can only be expressed as a function of A. Thus, the determination of the reaction depends only on A (call do pseudo-order). One thing to keep in mind is that the lower the reactants, the faster the reaction rate, not the excess reaction. Regarding isothermal adsorption,

I guess if the rx order should not affect the isotherm. Because isotherms are all at the heart of thermodynamics. I don’t know what this adsorption isotherm means. By definition, the adsorption isotherm denotes the quantity of A adsorbed on the surface at different concentrations of A in the gas or liquid phase, measured at ambient temperature. However, when the adsorption load is medium, more than one reactant (i.e. B) will affect the adsorption of another reagent (i.e. A) on the active surface. So sometimes it is not always advisable to flood a reagent in catalysis (especially in heterogeneous catalysis).
