Current Question (ID: 18331)

Question:
$\text{An incorrect statement about the collision theory of chemical reaction is:}$
Options:
  • 1. $\text{It considers reacting molecules or atoms to be hard spheres and ignores their structural features.}$
  • 2. $\text{The number of effective collisions determines the rate of reaction.}$
  • 3. $\text{The collision of atoms or molecules possessing sufficient threshold energy results in product formation.}$
  • 4. $\text{Molecules should collide in the proper orientation for the collision to be effective with sufficient threshold energy and proper orientation.}$
Solution:
$\text{HINT: Effective collision depends on threshold energy and proper orientation.}$ $\text{Explanation:}$ $\text{According to the postulates of collision theory, there are following necessary conditions for any reaction to occur}$ $\text{(i) Molecule should collide with sufficient threshold energy.}$ $\text{(ii) Their orientation must be proper.}$ $\text{(iii) The collision must be effective.}$ $\text{Not only sufficient threshold energy of colliding atoms or molecules is important for effective collision but also the proper orientation of molecules are also required for the formation of products.}$
