Answer:
Collision theory, theory used to predict the rates of chemical reactions, particularly for gases. ... Thus, according to the collision theory, the rate at which a chemical reaction proceeds is equal to the frequency of effective collisions.

The frequency factor A is proportional to the frequency of collisions with the right orientation.
Collision theory:
- According to collision theory, only a specific number of collisions between acceptable reactant particles with the proper orientation cause a detectable or noticeable change; these successful modifications are referred to as successful collisions.
- Specifically for gases, the collision hypothesis is used to forecast the rates of chemical processes.
- The collision theory is predicated on the idea that in order for a reaction to happen, the reacting species (atoms or molecules) must come into contact with one another or collide.
Probability factor:
- The ratio between the observed value of the rate constant and the one predicted by collision theory is the steric factor, also known as the probability factor.
- It can also be thought of as the preexponential factor to collision frequency ratio and is typically smaller than unity.
