potential 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..

Let us study another type of energy, called the potential energy. Potential energy is the energy that can be associated with the configuration (or arrangement) of a system of objects that exert forces on one another. If the configuration ..

: is the work done at a point by an external agent in moving a unit positive charge from infinity to a given point against the electrostatic field. ..

Water stored in a reservoir is capable of rotating turbines, which are kept at a lower level i.e, water stored in a reservoir possesses energy..

Consider an object of mass 'm', raised through a height 'h' above the earth's surface. The work done against gravity gets stored in the object as its potential energy (gravitational potential energy). Therefore, potential energy = work d..

In the previous chapter, we learnt about specific charge, its location, and its electric field, but here we are considering the potential energy of a charge, in an external field. Consider an external electric field 'E' produced by an external source, where it can specified or ..
