speed of reaction

Any chemical reaction requires a certain amount of energy to get initiated. This is called activation energy. Most of the molecules in a substrate have average kinetic energy, some have high energy and some have low energy. Under normal conditions of temperature only molecules with higher..

The rms speed of an oxygen molecule in a sample at 300 K is about 480m/s. This does not mean that the speed of each molecule is 480 m/s. Many of the molecules have speed less than 480m/s and many have speed more than 480m/s. Maxwell derived an equation givin..

Rate of reaction basically means the speed at which a chemical reaction occurs. The speed of a reaction is determined by monitoring the concentrations of the reactants or products at intervals of time. The volume of the reaction vess..

. On the other hand there are certain reactions which occur at an extremely slow speed. Examples of very slow reactions are: Rusting of iron Conversion of monoclinic sulphur to rhombic sulphur etc. In between very slow and very fast reactions, we have re..

. Nowadays other bombarding particles (i.e., projectiles) like protons ( 1 H 1 ), deutrons 1 H 2 electrons can be accelerated to very high speeds by fluctuating electric and magnetic fields in machines such as cyclotron, synchrotron etc. These high speed particles are more effic..

Rate of a Reaction - Rate of a reaction is defined as the speed at which the reactants are converted into product..

A catalyst usually speeds up the rate of reaction, although it is not consumed in the reaction. Oxidation of sulphur dioxide (SO 2 ) to sulphur trioxide (SO 3 ) is a very slow reaction. However, this reaction accelerates in the presence of nitric o..

The criterion for a chemical change is the production of one or more new substances. Therefore, certain conditions should be met in order to bring about a chemical change. The necessary conditions are: 1) A minimum amount of energy needed to initiate a reaction (activation energy) should ..
