Chemical Kinetics Conclusion
Conclusion - The rate of a reaction is measured in terms of change in concentration of a reactant or a product with time. Rate of a reaction is measured by following the concentration changes either by chemical analysis or by observing some other property such as color and optic..
Enzyme Catalysis
The formation of ES complex is fast and reversible, while the formation of the product (step 2) is the slow, rate determining step. The rate of enzyme catalyzed reaction changes from first order to zero order as the concentration of the substrate is increased..
Randomness and Spontaneity
Randomness and Spontaneity - In order to find out some other factor that may be responsible for the feasibility of a process, let us examine endothermic reactions. The simplest process occurring without any energy change (where D H is almost zero) may be illustrated wi..

The reactions in which a small molecule is removed from adjacent carbon atoms resulting in the formation of additional (multiple) bond between them are called elimination reactions. For example,..

Replacement Reactions - Aromatic diazonium salts undergo a large number of reactions. These reactions may be divided into two categories. i) Replacement reactions and ii) Coupling reactions..
Addition Reactions
Reactions in which two molecules react to form a single product are called addition reactions. For example, Depending upon the type of attacking reagent, the substitution or addition reactions are also classified as free radical, electrophilic or nucleop..

The reactions in which an atom or group of atoms in a molecule is replaced or substituted by different atoms or group of atoms are called substitution reaction. For example, These reactions can be of two types: ..

Fast reactions are generally ionic reactions. It is difficult to measure their rate..
Irreversible Reactions
The chemical reactions where the products do not combine to give the reactants are called irreversible reactions..
Reaction Intermediates
The species produced during cleavage of bonds are called reaction intermediates. The important reaction intermediates ar..

Very good, Tutor was clear and guided me through the whole algebra problems
This Tutor Vista is GREAT! loved this session, it helped me heaps.
It was a great pleasure working with this tutor was able to take me through the steps of my math problems which was very helpful because since I don't have lots of experience with math by the tutor doing the steps it helps me understand a great deal. Im so excited that Im finally getting this amazing service. We got so much done. thank you.
Incredible help, saved me from failing a test. Thank you so much. This tutoring is amazing! Explains things well, KUDOS - pam
