MHT CET 2024 Chemistry question

Which of the following is true for a reaction as per collision theory?

(A)Every collision between reactants leads to chemical reaction
(B)It may be expected that rate of reaction is equal to rate of collisionCorrect
(C)For gas phase reactions the number of collisions is far less compared to observed rate
(D)The colliding molecules do not need proper orientation

Answer: (B)

Solution

According to collision theory, the rate of a reaction depends on the number of collisions per unit time per unit volume, so it may be expected that the rate equals the collision rate; in practice the observed rate is much smaller because only effective collisions (energy at least the threshold energy and with proper
