Introduction - Processes by which substances are transformed to one or several products are called chemical reactions. Chemical processes that occur in the presence of light, like sunlight, are called photochemical reactions. These processes can occur naturally or under controlled conditions in the..

or The units of E k depend upon the units of R. Hence the following point holds true: The assumption of kinetic theory that the average kinetic energy or molecular velocity of any gas is directly proportional to its absolute temperature. K.E a u 2 ..

In order to explain the observed behaviour of gases, a model was proposed based on the molecular and kinetic concept of gas molecules. This model takes into account the particulate nature of matter and the constant movement of particl..

Kinetic Stability of Fuels - At normal temperature, fuels are stable even in the presence of air. This is because, the activation energy of combustion reaction is high. When a mixture of fuel and air is burned, a flame has to be applied, that is the mixture has to be ignited. Near the fla..

. Transition State explains the rate of reaction in term of formation of a transition state of reacting molecules. The formation of transition state requires energy of activation. Transition state theory connects kinetic rates with thermodynamic properties of reactants and the transition ..

At normal temperature, fuels are stable even in the presence of air. This is because, the activation energy of combustion reaction is high. When a mixture of fuel and air is burned, a flame has to be applied, that is the mixture has to be ignited. Near the flame, the contents are raised to high tem..

When a part of the metal is heated, the kinetic energy of the electrons in that region increases. Since the electrons are free and mobile, these energetic electrons move rapidly to the cooler parts and transfer their kinetic energy by means of collisions with other electrons. T..

When the volume of the gas is reduced, the molecules move with the same speed but in lesser space. As a result, the frequency of collisions with the walls of the container increases and a pressure increase is noticed. This is the statement of Boyle's law and this can be deduced from the kinet..
