What is chain reaction in chemical kinetics?

A chain reaction is a sequence of reactions where a reactive product or by-product causes additional reactions to take place. In a chain reaction, positive feedback leads to a self-amplifying chain of events.

What is reaction kinetics Slideshare?

KINETICS  Kinetics is the study of the rate of reactions, or how fast they occur under different conditions.  It usually includes a study of the mechanisms of reactions, which is a look at how the reacting molecules break apart and then form the new molecules.

What are the types of chain reactions?

Chain reactions can be addressed into two categories: first, controlled (like a nuclear power plant) and uncontrolled (an atomic bomb). Both are motivated by fission reactions, which are elaborated in this section.

What are the steps of chain reaction?

Chain reactions comprise initiation, propagation and termination steps. Initiation steps generate radicals from nonradicals, while termination steps generate nonradicals by removing radicals.

What is the application of chemical kinetics?

Through the study of chemical kinetics, it can reasonably guide us to know how to control the reaction conditions and improve the main reaction rate, in order to increase the production of chemical products, and also guide us to learn how to suppress or slow down the reaction rate of side reactions to reduce the …

Why it is called chain reaction?

chain reaction, in chemistry and physics, process yielding products that initiate further processes of the same kind, a self-sustaining sequence. So-called branching chain reactions are a form of chain reaction in which the number of chain carriers increases in each propagation.

Who invented chain reaction?

Enrico Fermi, the Italian-born Nobel Prize-winning physicist, directs and controls the first nuclear chain reaction in his laboratory beneath the bleachers of Stagg Field at the University of Chicago, ushering in the nuclear age.

What are the principles of chemical kinetics?

chemical kinetics, the branch of physical chemistry that is concerned with understanding the rates of chemical reactions. It is to be contrasted with thermodynamics, which deals with the direction in which a process occurs but in itself tells nothing about its rate.

What is kinetics in chemistry?

Kinetics •Studies the rateat which a chemical process occurs. •Besides information about the speed at which reactions occur, kinetics also sheds light on the reaction mechanism(exactly howthe reaction occurs). • John D. Bookstaver • St. Charles Community College

What is reaction kinetics (Vallance)?

Reaction Kinetics (Vallance) Reactions with simple rate laws: Reactions with complex rate laws*: * imply multi-step reactions (sequence of elementary steps) Simple and complex rate laws however, the overall rate cannot involve intermediate species

What is reaction mechanism?

Integrate d Rate Laws complicated Half-lifecomplicated k(T) • John D. Bookstaver • St. Charles Community College Reaction Mechanisms Reaction Mechanisms The sequence of events that describes the actual process by which reactants become products is called the reaction mechanism. • John D. Bookstaver • St. Charles Community College

What are the two theories of chemical reactions?

•Collision Theory: When two chemicals react, their molecules have to collide with each other (in a particular orientation) with sufficient energy for the reaction to take place. •Kinetic Theory: Increasing temperature means the molecules move faster.
