method catalyst

Higher hydrocarbons can also be cracked at lower temperature (600 - 650 K) and lower pressure (2 atm) in the presence of a suitable catalyst. Catalytic cracking produces gasoline of higher octane number and therefore this method is used for obtaining better quality gasoline. A ..

Fritz Haber Ammonia is prepared commercially in vast quantities. The major method of production is the Haber process invented by Fritz Haber, in which nitrogen is combined directly with hydrogen at high temperatures and pressures in the presence of a catalyst..

When vapours of primary or secondary alcohols are passed over copper gauze at 573 K, they get dehydrogenated to form aldehydes or ketones respectively. The dehydrogenation reaction is a better method of preparation because there is no risk of further oxidation of aldehyd..

Carboxylic acids are reduced to primary alcohols in the presence of strong reducing agent like lithium aluminium hydride. ..

1. From aldehyde and ketones - Aldehydes and ketones are reduced to the corresponding alcohols by a) Addition of hydrogen in the presence of catalysts like finely divided platinum, palladium, nickel and ruthenium. Aldehydes yield primary alcohols while ketones give secondary alcohol..

>A chemical equation is balanced so that the numbers of atoms of each type involved in a chemical reaction are the same on the reactant and product sides of the equation Equations must always be balanced. Equations are balanced by the hit and trial method. The rate of a chemical reaction depen..

A chemical equation is a shorthand way of describing the events that occur in a chemical change or reaction. The method of representing a chemical reaction with the help of symbols and formulae of the substances involved in it is known as a chemical equation. Exampl..

Enzymes are macromolecules, usually proteins, produced in living systems, which act as catalysts in physiological reactions. The striking characteristics of enzymes are their catalytic power and specificity. Enzymes have immense catalytic power; they accelerate reactions by factors of at..

(8 x 2) on the reactants side as well. Now the only unbalanced one is Chlorine. On the left hand side, there are 16 Cl. On the right hand side, firstly, there are 2 Cl in 2 KCl + 4 Cl in 2 MnCl 2 , making total of 6(2 + 4). Subsequently 10 more Cl atoms are to be accounted for. So place 5 in front ..

.e., its reaction is fast and more exothermic. This also implies that the reverse reaction becomes more difficult i.e., the more reactive a metal, the more difficult it is to extract from its ore. The metal is also more susceptible to corrosion with oxygen and water. The reactivity series can be es..
