What is another term used for the probability factor (P) in collision theory?
Updated On: Mar 27, 2026
- Temperature factor
- Compressibility factor
- Steric factor
- Concentration factor
Show Solution
The Correct Option is C
Solution and Explanation
Within collision theory, the probability factor, denoted as \( P \), is more accurately termed the steric factor. This theory elucidates the mechanisms of chemical reactions and the reasons for varying reaction rates. The steric factor specifically addresses the molecular orientation during collisions, influencing their potential to result in a reaction. Not every collision is reactive; successful reactions depend on appropriate orientation and sufficient energy. Essentially, \( P \) modifies the raw collision frequency to reflect the effective collision frequency that leads to a successful reaction. The steric factor underscores the significance of molecular orientation, offering an insight that surpasses simple collision enumeration.
