Chapter 7: Problem 4

According to the collision theory, the rate of a reaction depends on (a) the average collision of molecules (b) the total number of molecules (c) the number of colliding molecules per ml per unit time. (d) none of these

Short Answer

Expert verified
The correct answer is (c) the number of colliding molecules per ml per unit time.

Step by step solution

01

Understanding Collision Theory

The collision theory postulates that for a reaction to occur, it is not enough for particles to just collide. The particles must collide with enough energy (also called activation energy), and with the correct orientation.
02

Analyzing the options

Now examining the options given in the exercise, analyze each option and evaluate its relevance to the principles of collision theory. (a) The 'average collision of molecules' does not make clear sense in the context of collision theory. (b) The 'total number of molecules' might affect how many collisions are possible, but it doesn't impact the rate of the reaction per se – this is dictated more by concentration than total volume. (c) The 'number of colliding molecules per ml per unit time' indicates both the frequency of collisions (influenced by concentration and temperature) and the volume of the sample, which are relevant according to collision theory.
03

Choose the correct answer

Based on collision theory, the rate of a reaction depends not just on the number of collisions, but the number of effective collisions – those with sufficient energy and correct orientation. Thus, option (c) 'the number of colliding molecules per ml per unit time' is closest to these principles.
