Concept explainers
(a)
Interpretation: The points on the graph correspond to transition states are to be identified.
Concept introduction: The transition state is formed during the conversion of reactants into products in the
(b)
Interpretation: The points that correspond to reactive intermediates are to be stated.
Concept introduction: The transition state is formed during the conversion of reactants into products in the chemical reaction. In an energy level diagram, it corresponds to the high potential energy along the y-axis, while reactive intermediate has low potential energy.
(c)
Interpretation: The number of steps present in the reaction mechanism is to be identified.
Concept introduction: The number of steps in the reaction depends on the mechanism of the reaction. The activation energy
(d)
Interpretation: The each step of the mechanism is to be labeled as endothermic or exothermic.
Concept introduction: The chemical reaction in which energy is released during the formation of products is known as exothermic reactions. The energy released during the reaction is denoted by
(e)
Interpretation: The overall reaction as endothermic or exothermic is to be labeled.
