examples of slow reactions

Slow reactions are reactions that can be measured in the laboratories. e.g., hydrolysis of est..

If k 1 is very much less than k 2 that is k 1 << k 2 then the intermediate B is transformed into the product C as soon as it is forme..

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..

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 the reaction is, rate (r) = k..

All reactions are fast. At least, the individual steps of a reaction occur on an atomic time scale and are complete in less than 10 - 9 seconds. The net rate of a reaction is slow due to the slowness with which reactant molecules get activated or co..

Nuclear Fission - Two consequences of nuclear reactions are the phenomena of nuclear fission and nuclear fusion. Both are important sources of nuclear energy, which may be used for peaceful or destructive purposes. When a nucleus is bombarded with some sub-atomic particles such as a - par..

Rates of chemical reaction depends on the inherent characteristics or nature of the reactants. That is the reason, why some reactions are fast while others are slow. For E.g., oxidation of ferrous ion by KMNO 4 (potassium permanganate) in acidic medium is fast, while t..

Rate of Chemical Reactions - 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 reac..

Whenever a Lewis acid reacts with a Lewis base, a covalent bond is formed. For example, CO 2 (Lewis acid) reacts with OH - (Lewis base) to give HCO 3 - (bicarbonate ion), BF 3 (boron trifluoride) behaves as a Lewis acid and NH 3 (ammonia) as a Lewis base. Calcium oxide (CaO) behave..

Potassium, sodium, lithium and calcium react violently with dilute H 2 SO 4 and dilute HCl, forming the metal salt (either sulphate or chloride) and hydrogen gas. The reaction is similar to the reaction with water. Magnesium, aluminium, zinc, iron, tin and le..
