What are consecutive and parallel reaction?
Chemical processes in reality are mostly regarded as being consecutive, parallel, or mixed reactions of the two. The con- secutive reactions are those occurring sequentially through intermediates whereas the parallel reactions are others pro- ceeding along multiple pathways and resulting in branched products.
What are the different types of chain reaction?

What is an opposing reaction?
Hint:We have to know the definition of opposing reactions. Opposing reactions are the same as reversible reactions, where the products could again form reactants. Opposing reactions are distinct from reversible processes in thermodynamics. Generally, weak acids and weak bases undergo reversible reactions.
What is opposing reaction give one example?
(i) Dissolution of sodium chloride. (ii) Evaporation of water at 373K and 1atm pressure. (iii) Mixing of two gases by diffusion. (iv) Melting of ice without rise in temperature.
What is a consecutive reaction?
-Consecutive reactions consist of several steps of reaction in which the product of the first step will be the reactant of the next step and so on. -Consecutive reactions can also be referred to as complex reactions. Usually the product of the first reaction is called the intermediate.
What is a catalytic chain reaction?
From Wikipedia, the free encyclopedia. Catalytic chain transfer (CCT) is a process that can be incorporated into radical polymerization to obtain greater control over the resulting products.
What is the difference between controlled and uncontrolled chain reaction?
The difference between controlled and uncontrolled chain reactions is that controlled chain reactions do not lead to any explosive effects whereas uncontrolled chain reactions lead to explosive energy release.
What is a parallel reaction?
1) Parallel or competing reactions When a reactant gives two product (desired, and undesired) simultaneously with different rate constant then this is called a parallel reaction.
What is parallel reaction give example?
Examples of parallel reactions are (1)nitration of phenol with the formation of ortho-, meta-, and Pra-nitrophenol (identical reactants) and (2) nitration of a benzene and toluene mixture (nitric acid is the common reactant). This implied competing or parallel reactions.
What is the difference between homogeneous and heterogeneous catalysis?
Homogeneous catalysts are those which exist in the same phase (gas or liquid ) as the reactants, while heterogeneous catalysts are not in the same phase as the reactants. Typically, heterogeneous catalysis involves the use of solid catalysts placed in a liquid reaction mixture.
What is catalysis explain with examples?
Catalysis is the causing of the acceleration of a chemical reaction. For example, reactants and catalyst are all gases. A heterogeneous catalysis is a form of catalysis in which the catalyst is in different physical state than the reactants.
What are parallel reactions?
The parallel reactions are also called as side reactions. The reactant A reacts to give products B,C,D separately by following three different reaction pathways involving different k1, k2, k3 rate constants respectively.
What are consecutive or sequential reactions?
The reactions in which the reactant forms an intermediate and the intermediate forms the product in one or many subsequent reactions are called as consecutive or sequential reactions. In such reactions the product is not formed directly from the reactant. Various steps in the consecutive reaction are shown as below :
What is the difference between simple reaction and complex reaction?
Simple And Complex Reactions : Difference and Types. A simple reaction takes place in a single step. Simple reactions are also known as elementary reactions. One step reactions are elementary reactions. In some reactions many side reactions occur along with the main reaction involving product formation.
What is the difference between main reaction and side reaction?
Among the many side reactions, the reaction in which maximum yield of the product obtained is called as the main or major reaction while the other reactions are called as side or parallel reactions. In opposing reactions the products formed react back simultaneously to form the reactants.
