Chemical Kinetics Question 15
Question: The reason for almost doubling the rate of reaction on increasing the temperature of the reaction system by $ 10^{o}C $ is [J & K 2005]
Options:
A) The value of threshold energy increases
B) Collision frequency increases
C) The fraction of the molecule having energy equal to threshold energy or more increases
D) Activation energy decreases
Show Answer
Answer:
Correct Answer: B
Solution:
When the temperature is increased, heat energy is supplied which increases the kinetic energy of the reacting molecules. this will increase the number of collisions and ultimately the rate of reaction will be enhanced.
