Heating is continued for 8-10 hours. During this time haematite oxidises the impurities like carbon, silicon, sulphur and phosphorus. Carbon is removed as carbon monoxide, sulphur as sulphur dioxide, silicon as silica and phosphorus is oxidised to its pentoxide. These oxides react with li..

. Average rate of a reaction does not represent the actual rate of a reaction at any instant of time. From the figures 6.1 and 6.2 it is clear that the rate of reaction actually decreases with time. This is because the rate of reaction dep..

takes place only in the presence of sunlight. In this reaction, the light energy from the sun is absorbed by the photosynthetic pigments and is used to break down the water molecules. This is called the photolysis ('photo' is light and 'lysis' refers to break down) of water. This rele..
First Order Reaction
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 the reaction..

The rate of a reaction is broadly defined as the speed with which the reactants are converted into products. This can be determined both quantitatively and qualitatively. Qualitatively, (concerned with or depending on constitiuents) an idea about the rate of a reaction can be o..

F.F. Blackman (1905) demonstrated the presence of the dark reactions for the first time. It utilises the chemical energy temporarily stored in the products of light reaction. It is also called the Calvin cycle. It is a series of reactions taking place in a c..

It is a common observation that most of the reactions when carried out in closed vessels do not go to completion, under a given set of conditions of temperature and pressure. Infact in all such cases, in the initial state, only the reactants are present but as the reaction proce..

Half Life of a Reaction - Half life of a reaction is defined as the time required for reducing the concentration of a reactant to half its initial value. It is denoted as t 1 / 2 . As discussed before, the t 1 / 2 of a zero order reaction is given as In gener..

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..

The concentration ratio, i.e., the ratio of the product of concentration of the products to that of the reactants at any time (t) is known as the concentration quotient 'Q' of the reaction at time (t). The value of Q c or Q p will be different from the value of..
