Chemistry - Chemical Kinetics Question with Solution | TestHub
Which of the following is true for a reaction as per collision theory?
Options:
Answer:
Solution:
According to the collision theory of bimolecular reactions, chemical reactions occur as a result of collisions between reactant molecules. Based on this, it may be expected that the rate of reaction is equal to the rate of collision.
However, the other statements are incorrect because:
1. Not every collision leads to a chemical reaction; only effective collisions (with sufficient energy and proper orientation) result in a reaction.
2. For gas-phase reactions, the number of collisions is far greater (not less) compared to the observed rate of reaction.
3. The colliding molecules must have proper orientation to form the products.
Thus, the only true statement among the given options is that it may be expected that the rate of reaction is equal to the rate of collision.
Answer: It may be expected that rate of reaction is equal to rate of collision.
