B. Number of effective collisions determines the rate of reaction.
C. Collision of atoms or molecules possessing sufficient threshold energy results into the product formation.
D. Molecules should collide with sufficient threshold energy and proper orientation for the collision to be effective.

Ans: Correct option C
In the case of gases, collision theory is used to predict the speeds of chemical processes. According to this idea, the reacting chemicals must collide with enough energy and in the right direction. The molecules travel quicker and the frequency increases as the temperature rises.
This proves that all three other possibilities, A, B, and D, are correct. Option C does not correspond to the correct answer.

Reaction rate is used to measure how fast or slow reactions occur per unit time. The rate constant is a proportionality factor that remains constant for every reaction.
Yes, in elementary reactions, order and molecularity can be the same, but this is not always the case because order is an experimental quantity, and molecularity is a theoretical concept.
Reaction Kinetics, also known as chemical kinetics, is the study of the rate of chemical reaction and the factors affecting the reaction rate, such as temperature, concentration, and catalyst.
