activation energy of parallel reactions

Example 11: The rate constants of reaction at 700 K and 760 K are 0.011M - 1 s - 1 and 0.105 M - 1 s - 1 respectively. What are the values of 'A' and 'E..

Concept of Activation Energy - For a reaction to occur, reactant molecules must collide with each other. Only those collisions result in product formation which have energy equal or more than a certain minimum energy. This energy is called..

For a reaction to occur, reactant molecules must collide with each other. Only those collisions result in product formation which have energy equal or more than a certain minimum energy. This energy is called the threshold energy. This implies..

The importance of the above reactions lies in the production of nitric acid, which is a very important industrial produc..

Parallel Reactions - A parallel reaction is of the following type in which a reactant A transforms itself to two different products B and C. The rate expressions for the reactant and the products are, The solution to these equations are as follo..

Alkyl halides readily combine with active metals like sodium, magnesium, cadmium, lithium et..

Energy Transfer and Energy Transformation - Energy is the capacity to do work. All living organisms require energy for carrying on their vital metabolic activities. The primary source of energy for living system is solar radiation. The rad..

It is the step in which each of the participating amino acid reacts with ATP to form amino acid AMP complex and pyrophosphate. The reaction is catalyzed by a specific amino acid activating enzyme called aminoacyl-tRNA synthetase in the presence of Mg2+. There is a separate amin..

Collision Theory - From Arrhenius equation, it is seen that the rate constant k of a reaction increases with temperature and therefore, the rate of reaction also increases. Why does k depend on temperature? This can be explained, to a certain extent, by collision theory. Accordi..

Every substance possesses a definite quantity of energy, under a given set of factors such as chemical nature of the substance, temperature and pressure. The total energy contained in a system or substance is called its internal energy or intrinsic energy..
