Current Question (ID: 18303)

Question:

$\text{Select the correct option based on statements below:}$ $\text{Assertion (A): At very high temperatures (approaches to infinity), the rate}$ $\text{constant becomes equal to the collision frequency.}$ $\text{Reason (R): The collision in which molecules collide with proper orientation}$ $\text{is called an ineffective collision.}$

Options:

1. $\text{Both (A) and (R) are true and (R) is the correct explanation of (A).}$
2. $\text{Both (A) and (R) are true but (R) is not the correct explanation of (A).}$
3. $\text{(A) is true but (R) is false.}$
4. $\text{Both (A) and (R) are false.}$

Solution:

$\text{HINT: Rate = } Z_{AB} e^{-E_a/RT}$ $\text{Explanation:}$ $\text{At very high temperature (approaches to infinity) rate constant becomes}$ $\text{equal to collision frequency because}$ $\text{rate = } Z_{AB} e^{-E_a/RT} , \text{ when T trends to infinity } e^{-E_a/RT} \text{ became one, and rate = } Z_{AB}.$ $\text{The collision in which molecules collide with proper orientation is called an}$ $\text{effective collision. Hence, Assertion is a true statement but the reason is}$ $\text{false.}$
