What describes the potential energy diagram of an exothermic reaction?
The potential energy of the reactants is greater than the potential energy of the products.
What does a positive delta H look like on a potential energy diagram?
A positive delta H on a potential energy diagram indicates that the products of a reaction have higher potential energy than the reactants, signifying that the reaction is endothermic. On the diagram, this is represented by a curve that rises from the reactants to the products. The energy difference between the reactants and products is shown as a vertical distance, illustrating the heat absorbed during the reaction. The activation energy may also be indicated, showing the energy required to initiate the reaction.
How is an exothermic reaction identified on a potential energy diagram?
An exothermic reaction is identified on a potential energy diagram by observing that the energy of the products is lower than that of the reactants. This is depicted as a downward slope from the reactants to the products, indicating that energy is released during the reaction. The difference in height between the reactants and products represents the amount of energy released (enthalpy change, ΔH) in the process. Additionally, the activation energy is shown as a peak that must be overcome for the reaction to proceed.
Whats the difference between activation energy and the change of energy in a PE diagram?
Activation energy is the minimum energy required for a reaction to occur, while the change in energy in a potential energy diagram represents the difference in energy between the reactants and the products of a reaction. Activation energy is specific to the transition state of a reaction, whereas the change in energy is a measure of the overall energy difference between reactants and products.
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 statement describes the potential energy diagram of an exothermic reaction?
The difference in potential energy between the reactants and products.
Looking at a free energy diagram for an equilibrium reaction which of the following scenarios will favor the formation of more reactant?
The concentration of reactants is less than the concentration of reactants at equilibrium. The concentration of products is greater than the concentration of products at equilibrium.
What statement best describes the potential energy diagram of an endothermic reaction?

What does the potential energy diagram of a chemical reaction tell you?
A potential energy diagram of a chemical reaction illustrates the energy changes that occur as reactants are converted into products. It shows the activation energy required for the reaction to proceed and whether the overall process is exothermic or endothermic. The diagram can also reveal the stability of the reactants and products.

The potential energy of the products is greater than the potential energy of the reactants.
What does a positive H look like on a potential energy diagram?
The potential energy of the products is greater than the potential energy of the reactants.
What is an activation energy diagram in chemistry?
Activation energy in chemistry is the amount of energy required to start a reaction. For every chemical reaction, a certain amount of energy is required to start it. The diagram represents how much energy it takes to do this, and also shows how much energy you get from it. With this diagram, you can also calculate the energy of products, reactants, e.t.c. This is also a useful diagram to explain the function of a catalyst, something used to decrease the activation energy.
