Chapter 16.1, Problem 4SSC

Interpretation Introduction

Interpretation:

The relation between collision theory and the reaction rate needs to be explained.

Concept introduction:

According to the collision theory, collision of reacting molecules in correct orientation with sufficient energy leads to form an activated complex. Activated complex is also termed as transition state, which is temporary and possess unstable arrangement of atoms where old bonds breaks and new bonds formed. Due to this, activated complex may form products or may breaks to form the reactants.

Explanation of Solution

The collision theory states that the collision of two particles with enough energy and proper orientation results chemical reaction. So, the relation of this with reaction rate is very simple. Reaction rates are specific to certain reaction as the occurrence of chemical reaction is always at the same geometry. Taking reference to energy, the application of collision theory, such as reaction of hydrogen and oxygen to form water, a match that give molecules enough energy to undergo collision and results chemical reaction.

Conclusion

The collision theory states the product will form when the reacting molecules collide with each other with proper orientation.
