order and molecularity of a reaction

Elementary reactions are classified according to their molecularity. The number of reacting species, which are involved in simultaneous collision to bring about a chemical reaction is called the molecularity of the reaction. In a unimolecular r..

Order of a Reaction - The order of reaction is determined with respect to each reactant in the reaction. The order of a reaction is the power to which the concentration of a reactant is raised. This is the order with re..

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..

Example 7: Hydrogen (H 2 ) gas reacts with bromine (Br 2 ) gas to give hydrogen bromide vapor. The chemical reaction is represented by the equation as follow..

A complex reaction involving two series reactions can be of the type, ..

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..

For a reaction A + B C + D. The rate law for the reaction is expressed as rate = k [A] m [B] n If the concentration of B is kept large, then [B] essentially does not change over time and if the rate of reaction is determined as rate = k [A] then this reaction..
