multiple choice 2 points\nprovide an energy profile diagram for an exothermic one - step reaction and label the reactants, products, transition states, activation energies (eₐ), and δg°, if applicable.
Answer
Answer:
The first diagram is correct.
Explanation:
Step1: Understand exothermic reaction
In an exothermic one - step reaction, the energy of the products is lower than that of the reactants.
Step2: Analyze energy profile
The first diagram shows reactants at a higher energy level, a transition state at the peak, activation energy ($E_a$) as the energy difference between reactants and transition state, and products at a lower energy level with a negative $\Delta G^{\circ}$ (difference in energy between reactants and products). The second diagram has no $\Delta G^{\circ}$ label and does not clearly show the energy relationship between reactants and products for an exothermic reaction.
