An energy diagram for an exothermic reaction illustrates the energy changes during the reaction process. It typically features the reactants at a higher energy level than the products, indicating that energy is released as the reaction proceeds. The diagram also shows an energy barrier, or activation energy, that must be overcome for the reaction to occur. The overall decrease in energy from reactants to products reflects the exothermic nature of the reaction, signifying that heat is released into the surroundings.

What statement describes the potential energy diagram of an exthermic reaction?
In an exothermic reaction, the potential energy diagram shows a decrease in potential energy as the reactants transform into products. The reactants have higher energy compared to the products, indicating that energy is released during the reaction, often in the form of heat. The diagram typically features a downward slope from the reactants to the products, with an activation energy barrier that must be overcome for the reaction to proceed. Overall, this results in a negative change in enthalpy (ΔH).
What will the profile for endothermic and exothermic with the catalyst added?
In the presence of a catalyst, both endothermic and exothermic reactions will have their activation energy lowered, allowing them to proceed more quickly. For endothermic reactions, the overall energy profile shows a reactant state with lower energy than the products, but the catalyst reduces the energy barrier for the transition state. In exothermic reactions, the reactants start at a higher energy level than the products, and again, the catalyst facilitates the reaction without altering the energy difference between reactants and products. Thus, while the catalyst speeds up the reaction, it does not affect the overall energy change (ΔH) for either type of reaction.
What does a positive H look like on a potential engery diagram?
In a potential energy diagram, a positive enthalpy change (ΔH) indicates that the reaction is endothermic, meaning it absorbs energy from the surroundings. This is visually represented by the products being at a higher potential energy level than the reactants. The diagram typically shows an upward slope from the reactants to the products, with the energy barrier for activation also depicted as a peak. Overall, the diagram highlights that energy is required for the reaction to proceed.

What is the relationship between an energy diagram and activation energy in a chemical reaction?
An energy diagram shows the energy changes that occur during a chemical reaction. Activation energy is the minimum amount of energy required for a reaction to occur. In the energy diagram, the activation energy is the energy barrier that must be overcome for the reaction to proceed. A higher activation energy means a slower reaction, while a lower activation energy means a faster reaction.
