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 is MBBS is different from BDS?

After graduating from high school in India, many students pursue careers in medicine through NEETInstitute Dehradun . Since many students have wanted to be doctors since they were young, they decided to focus on physics, chemistry, and biology as their primary subjects after class ten. The two most well-liked medical degrees in India are the MBBS and the BDS. The most common course choice confusion among students is between MBBS(Bachelor of Medicine, Bachelor of Surgery) and BDS(Bachelor of Dental Surgery). It is a result of their need at NEET Institute Dehradun for more knowledge regarding the scope and significance of both courses. At Genesis NEET Classes Dehradun, each of the MBBS and BDS programs has value and offers a variety of rewarding career options. A student must pass the NEET UG exam and obtain the NEET Cut off score set by the NTA to be eligible to enroll in an MBBS or BDS program in India. Additionally, candidates must fulfil the following criteria: ● ...
