specific rate of reaction between reaction of ammonia and air

Ammonia - Ammonia was known to mankind since a long period, as it was produced in nature by putrefying and ammonifying bacteria. Chemical compound, NH 3 colorless gas that is about one half as dense as air at ordinary temperatures and pressures. It ..

, Cisplatin, a compound with a molecular formula of Pt (NH 3 ) 2 Cl 2 is used in chemotherapy of cancer. It reacts with water and releases chloride ion bound to central platinum metal. The reaction is represented as: The rate at which this reaction ..

Example 2: The gaseous phase decomposition of dinitrogen pentoxide (N 2 O 5 ) to nitrogen dioxide (NO 2 ) and oxygen (O 2 ) is given by, For the reaction the concentration of O 2 was monitored and the following data were obtained. Time/s 0 600 1200 1800 3000 4200 [O 2 ..

Everyday experience tells us that chemical reactions take place in widely varying rates. Infact rates of various reactions vary from very slow to very fast. Some reactions are so rapid that they occur as soon as the reactants are mixed. For example..

First Order Reaction - Example 5: Cyclopropane (C 3 H 6 ) at room temperature has a ring structure. When it is heated, the ring opens up and cyclopropane isomerizes to propylene. The reaction takes place in a first order manner. Therefore, the rate law for th..

Mechanism of Reaction - A balanced chemical equation represents the overall result of a chemical reaction. However, at the molecular level, more than one reaction step might be involved. Most reactions can be broken down into a sequence of elementary rea..

) gets positively charged due to the deficiency of electrons. When a metallic wire connects the two electrodes, the electrons flow from the negatively charged electrode to the positively charged electrode. Thus, in an indirect redox reaction, electrons flow in a particular direction throu..

>These reversible reactions never go to completion if performed in a closed container. For a reversible chemical reaction, an equilibrium state is attained when the rate at which a chemical reaction is proceeding in forward direction equals the rate..

. However, at higher concentrations the surface of the catalyst becomes fully covered and any further increase in the concentration of the reactants does not affect the rate of the reaction. One very common example, is the decomposition of ammonia (NH 3h..

Example 4: Ammonia (NH 3 ) gas decomposes over platinum catalyst to nitrogen gas (N 2 ) and hydrogen gas (H 2 ). The chemical reaction is as follows: fig 6.4(a) - Concentration versus time profile for a zero order reaction..
