Given below are two statements:
Statement I: The collision frequency 
is the number of molecular collisions per unit volume per unit time.
Statement II: For many reactions, increasing the temperature by 
makes the rate constant roughly 2-3 times larger.
In the light of the above statements, choose the most appropriate answer from the options given below:
Text Solution
Verified by ExpertsC
(I): In collision theory, collision frequency 
number of collisions per unit volume per unit time - correct.
(II): For many reactions, a 
rise increases k about 2-3 times (temperature coefficient), also correct.
