Chapter 16, Problem 11E

Interpretation Introduction

Interpretation:

The energy profile diagram for the reaction involving the formation of hydrogen chloride is to be drawn. The axes for energy and axes for the progress of the reaction is to be labeled. The reactants, products, transition state, activation energy, the energy of reaction are to be labeled.

Concept introduction:

Reaction profile diagram shows the change in energy as the reaction progress. The transition state is the topmost point on the reaction profile diagram where bond breaking and new bonds formation takes place. Activation energy is the amount of energy required to convert reactants into transition state. In an endothermic reaction, heat is absorbed. In an exothermic reaction, heat is evolved.
