(a)
Interpretation: Each reaction is to be labeled as endothermic or exothermic.
Concept introduction: The
(b)
Interpretation: The faster reaction is to be identified.
Concept introduction: The activation energy
(c)
Interpretation: The reaction which generates the product lower in energy is to be identified.
Concept introduction: The activation energy
(d)
Interpretation: The point in energy level diagrams which corresponds to the transition state is to be identified.
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.
(e)
Interpretation: The activation energy id to be labeled for each reaction.
Concept introduction: The activation energy
(f)
Interpretation: The change in enthalpy
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
