Chapter 16.1, Problem 9SSC

Interpretation Introduction

Interpretation:

The existence of an activated complex during chemical reaction needs to be explained.

Concept introduction:

Chemical kinetic is the branch of chemistry that deals with kinetic or rate of a chemical reaction. The rate of reaction can be defined as the change in the concentration of reactant and product with time. The rate of reaction mainly depends on the activation energy.

In a chemical reaction to be occurred; two most important requirements are activation energy to reactant molecule and correct orientation of reactant molecules to colloid and form product.

Answer to Problem 9SSC

The energy profile curve proves the existence activated complex.

Explanation of Solution

Given information:

The activated complex is formed during the chemical reaction.

A chemical reaction can involve one or multiple steps during the conversion of reactant to product. The minimum energy that is required for the conversion reactant to product is called as activation energy.

Once the reactant molecules acquire activation energy, they form activated complex which is highly unstable due to highest energy and readily converts to product.

Conclusion

Thus,
