A pseudo unimolecular reaction refers to a reaction mechanism where overall kinetics mimic those of a unimolecular reaction, but involve multiple molecules coming together in a step-wise process. This can occur when a stable intermediate is formed that dictates the rate of the reaction, making it appear unimolecular even though it involves multiple reactant molecules.

What is SNi reaction?
The question is probably intended to be about SN1 reaction. See the following from Wikipedia, accessed Feb. 25, 2013: "The SN1 reaction is a substitution reaction in organic chemistry. "SN" stands for nucleophilic substitution and the "1" represents the fact that the rate-determining step is unimolecular".
Calculation for pseudo first order reaction?
To determine the rate constant k for a pseudo-first order reaction, you can plot the natural logarithm of the concentration of reactant vs. time. The slope of the resulting line will be equal to -k. This approach is often used for reactions where one reactant is present in excess and its concentration remains constant throughout the reaction.
What is the difference between an E1 and a Sn1 reaction?
in sn1 reaction the electrophile leaves the substrate forming a carboncation.afterwards the nucleophile while attack the carboncation and usually recimes may be formed in sn1 reaction depending on whether the carboncation experienced a front of backside attack. in sn2 reaction the departing and attacking proccess occurs at the same time. these is pule rampai from the university of johannesburg

Do centripetal and centrifugal reaction constitute action-reaction pair?
No, centripetal and centrifugal reactions do not constitute an action-reaction pair. Centripetal force acts towards the center of rotation to keep an object moving in a circular path, while centrifugal force is a pseudo-force that appears to act outward on the object in the rotating frame of reference. These forces do not follow Newton's third law of motion as an action-reaction pair.
Define Pseudo unimolecular reaction with example?
there is no meaning in pseudo unimolecular reaction. Explanation: molecularity of a reaction is "the no. of species(ions, molecules or atoms) which collide simultaneously to give rise a chemical change or chemical reaction. a reaction can be called unimolecular (decomposition of ammonium nitrite to nitrogen and water) as single molecule decomposes to give rise to products a reaction can be called bimolecular (HI decomposes to H2 and I2) as two HI molecules are colliding. that means molecularity says about "actually how many species collide and there is nothing ambiguity (pseudo) in it. but a reaction can be called pseudo first order reaction (hydrolysis of sucrose) as rate of reaction depends on only sucrose conc. and water solvent conc. as is in excess do not affect the rate. if any one is having doubts in chemistry u can mail me at chemistry_krish@yahoomail.com
The reaction type that has only one reactant is?
The reaction type that has only one reactant is called a unimolecular reaction. In a unimolecular reaction, a single reactant molecule undergoes a chemical transformation to form one or more products. An example of a unimolecular reaction is the thermal decomposition of a single molecule.

What is the significance of rate constant?
A coefficient of proportionality relating the rate of a chemical reaction at a given temperature to the concentration of reactant (in a unimolecular reaction) or to the product of the concentrations of reactants.

What type of reaction is the hydrolysis of t butyl chloride?
The hydrolysis of t-butyl chloride is a nucleophilic substitution reaction, specifically a unimolecular SN1 reaction. This reaction involves the attack of a nucleophile (water) on a carbocation intermediate formed from the t-butyl chloride.
Is a secondary alkyl halide more likely to undergo an SN1 or SN2 reaction?
A secondary alkyl halide is more likely to undergo an SN1 (substitution nucleophilic unimolecular) reaction due to the stability of the carbocation intermediate formed in the reaction.
Why adsorption follows pseudo orders?
is because is not chemical reaction

How can one determine the molecularity of elementary reactions?
The molecularity of an elementary reaction can be determined by looking at the number of reactant molecules involved in the reaction. If only one reactant molecule is involved, the reaction is considered unimolecular. If two reactant molecules are involved, the reaction is bimolecular. And if three reactant molecules are involved, the reaction is termolecular.

Molecularity of chemical reaction?
Molecularity of a chemical reaction refers to the number of reactant molecules participating in a elementary reaction step. It provides information about the number of molecules colliding to form products in a single step. For example, a unimolecular reaction involves only one reactant molecule, while a bimolecular reaction involves two reactant molecules.
