Interpretation Introduction

(e)

Interpretation: An energy diagram and the structure of the transition state are to be drawn by assuming Equation [1] as an endothermic reaction. The axes, reactants, products, $E_{\text{a}}$, and $\Delta H°$ in an energy diagram are to be labeled.

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. In this state, the dashed bond implies that bonds are partially broken and partially formed in the reaction.

Interpretation Introduction

(f)

Interpretation: An energy diagram and the structure of the transition state are to be drawn by assuming Equation [2] as an endothermic reaction and the energy of product of the rate-determining step is higher than the reactants or products. The axes, reactants, products, $E_{\text{a}}$, and $\Delta H°$ in an energy diagram are to be labeled.
