Rate of chemical reaction and its relation with collision frequency and energy and probability factor
Rate of chemical reaction
In terms of collision, chemical reaction is occurs due to collision of sufficient energy and orientation. The rate of chemical reaction is equal to the collision frequency multiplied by energy factor and probability factor. The rate of reaction is exactly the rate of effective collision happening.
collision frequency and reaction rate
The factors dependent on collision frequency are particles crowded situation, how crowded the particles are? This crowding of particles are the pressure and concentration. Hence the significant relationship are found in concentratuon and pressure with chemical reaction rate. Particles sizes are also a factor of collision frequency. The movement of particles are also a dependent factor of collision frequency. The speed of movement of the particles are concerned with the temperature and weight of the particles. Collision frequency rises with the rising of the temperature. With the increasing of collision frequency the rate of chemical reaction is also increases. Hence, it is to say that with the increasing of the temperature the rate of chemical reaction is also increases.
Probability factor and energy factor
The probability factor is concerned with the geometry of the particles.In a closely related chemical reaction the probability factor of two reaction seems to same as close as possible. For a chemical reaction, besides of the kinetic energy of the moving molecule another energy should be provided. Hence the probability factor depends not only with the atoms in a molecule concerned with collision but also with the alignment of the atom.
