uses of chemical kinetics

Processes by which substances are transformed to one or several products are called chemical reactions. Chemical processes that occur in the presence of light, like sunlight, are called photochemical reactions. These processes can occur naturally or under controlled condit..

. Transition State explains the rate of reaction in term of formation of a transition state of reacting molecules. The formation of transition state requires energy of activation. Transition state theory connects kinetic rates with thermodynamic properties of reactants and the transition ..

Energy - Energy is a number that we associate with a system of one or more objects. If a force acts on one of the objects, making it move, then the number changes. After countless experiments, scientists and engineers realised that if the scheme by which we assign these energy numbers is planned ca..

>Matter consists of molecules. These are the smallest particles, which are capable of free existence and retain all the chemical properties of the parent substance. The molecules are always in a state of random continuous motion. The molecules exert forces on one another. These forces dep..

It is a symbolic notation that uses formulae instead of words to represent a chemical equation..

Chemical fertilizers contain a higher amount of nutrients as against manures and so are used in very small quantitie..

Chemicals added to food materials to prevent the growth of micro organisms or prevent spoilage and to increase their shelf life are called preservatives. Some examples are given below: Sodium benzoate is used as a preservative for fruits, fruit juices, jams and squashes. 0.06% t..

Chemicals find great use in cosmetics. Creams like cleansing creams, cold creams, bleaching and vanishing creams are prepared synthetically from chemicals. Perfumes, talcum powders and deodorants are also some other cosmetic substances that are obtained from chemi..

Chemical Fertilizers - These are nutrient supplements for plants manufactured in fertilizer factories from chemicals. They are nutrient specific i.e., they may provide only nitrogen, only phosphorus or only potassium to the soil. They are often used when a particular n..
