Chemical Kinetics: A key branch of Physical Chemistry

The feasibility of a given reaction can be predicted with the help of their dynamic principles. Besides this the relative amount of reactants and products at equilibrium position of the reaction can also be predicted. In addition, we can predict whether changes in the experimental conditions will increase or decrease the amount of products at equilibrium. However, thermodynamic principles do not provide any information regarding the speed of the given reaction, i.e., how much time a given feasible reaction will take for its completion. Moreover, it is not possible to predict how the speed of a given reaction gets affected by changing the experimental conditions. The study of rate of reaction or by changing the experimental conditions.

The study of rate of reactions including its dependence on the concentration. The important topic of physical chemistry is known as chemical kinetics. The important application of the study of rate of reaction is to use the kinetic data in establishing the molecular pathway or mechanism by which the reaction takes place. Chemical kinetics is essential for CSIR NET Coaching in Chemistry. It is also very useful for Chemistry JAM coaching.Rate of Reaction and Rate of Reaction Divided by Constant Volume

Average Rate of the Amount of a Reactant or a Product

Reactions with wide difference in speeds are known. Some reactions proceed at very fast speed and some are very slow. It depends on reactants concentration, nature of reactants, temperature, nature of products formed, surface area, catalyst and surface area of reactants. In some cases, the speed is so fast that the reaction appears to be instantaneous, e.g., reactions are known which proceed at very slow speeds. Kinetics is the most versatile branch of Chemistry.It is very essential for CSIR NET Coachinhg in Chemistry, also very very useful branch of Chemistry for ‘Chemistry JAM coaching’

Laws of Crystallography: boon in Solid State Chemistry

Laws of crystallography Crystallography is the branch of science which deals with the geometry, properties and structure of crystals and crystalline substances. It is based on three fundamental laws. The law of constancy of interfacial angles : It states that the size of the faces or even shapes of the crystals of a substance may vary widely with conditions of crystallization yet the interfacial angles between any two corresponding be 90˚ , irrespective of the size and shapes of faces. The measurement of crystal angles is important in the study of crystals. * Interfacial Angles- The crystals are bound by plane faces. The angle between any two faces is called an interfacial angle. It is indicated from the above figure that the shapes of crystals are different but the angle between any two corresponding faces is 90˚. 2. Law of rational indices (Hauy’s law): This law states that “the ratio between the intercepts on the axes for the different faces ...

An Introduction to Organometallic Chemistry

The compounds which contain bond between carbon atom and the atoms which are more electropositive than carbon are known as Organometallic compounds. An Organometallic compound contains atleast one direct metal-carbon (M-C) bond, but it is not a rigid condition. The carbon containing groups may be carbonyl, alkyl, alkene, alkyne, aryl, allyl, cyclic, or heterocyclic. This topic is essential for CSIR NET coaching in chemistry . It is also beneficial topic for IIT JAM coaching in Chenistry. Eg:- (i) Organo-magnecium compounds  RMgX (Grignard Reagent) (ii) Organo-copper compounds  R2CuLi (Gilmann Reagent) (iii) Organo –lithium compounds  RLi (R = -Ph, -Bu…..) Some Important Exceptional Cases:- Eg:-(1) Metal carbides and cyanides are not Organometallic compounds i.e. CaC2, NaCN. Eg:-(2) Wilkinson catalyst :-It does not contain any M-C bond, even though it is a very important Organometall...

How To Prepare Better For The Upcoming NEET?

The school studies limit you from fighting competition, and that's why joining NEET coaching stands one step ahead . Accompanying the studies, you need techniques for solving questions taught only by experts. So, it is wise to join NEET UG coaching in Dehradun as earliest. Thus, you'll learn tricks to utilize the time to its maximum and prepare better in the following segment. 1. Study Material Choosing the suitable study material is a bit tricky because everything seems promising. However, with the help of your mentors and fellow students, choose the study material which seems maximum relevant to NCERT. Also, the same applies to practice papers and reference books. 2. Join the Classes If you think; you got the syllabus and can prepare for NEET-UG by yourself, you're mistaken as you need guidance to study it. So, you must join NEET offline & online classes depending upon your preference for...
