rotational energy barrier

Energy Barrier - In this theory, the rate constant is related to three factors Z, f and p by the equation k = Zfp b (19) where Z is the collision frequency f is the fraction of collisions having energy greater than the threshold energy and p is the fraction o..

From Arrhenius equation, it is seen that the rate constant k of a reaction increases with temperature and therefore, the rate of reaction also increases. Why does k depend on temperature? This can be explained, to a certain extent, by collision theor..

. Collision theory explains the temperature dependence of rate of a reaction based specifically on the concept of effective collisions. However, collision theory does not account for the role of activation energy influencing the rate of a reaction. Another theory that was proposed a few y..

Kinetic Energy - It is a matter of common experience that a fast moving stone can break a windowpane, falling water can rotate turbines and moving air can rotate windmills and propel sailboats. In all these examples, the moving body possesses energy. Work is ..

Wind Energy - Wind energy is one of the first sources of energy known to man. The sun's rays are stronger nearer the equator than in the polar region. This heats the air in equatorial region and warm lighter air rises while cooler polar air moves in to replace it. This..

Flowing or moving air is called wind. By the virtue of this motion, the wind possesses kinetic energy. A windmill is used to make practical use of wind energy. The force of the wind rotates the blades of the windmill. Wind should flow continuously with certain minimum..

Study the Following Examples: - Water stored in a reservoir is capable of rotating turbines kept at a lower level. Water stored in a reservoir possesses energy by virtue of its position. A nail hit hard with a hammer gets fixed while if the hammer is just placed on the nail, the..
