Chemical Kinetics Ques 42
42. An increase in the concentration of the reactants of a reaction leads to change in
[2020]
(a) heat of reaction
(b) threshold energy
(c) collision frequency
(d) activation energy
Show Answer
Answer:
Correct Answer: 42.(c)
Solution:
(c) The number of collisions per second per unit volume of the reaction mixture is known as collision frequency $(Z)$. collision frequency $\propto$ no. of reacting molecules or atoms. Higher the concentration of reactant molecules higher is the probability of collision and so the collision frequency.
