What statement describes the potential energy diagram of an exothermic reaction?
The difference in potential energy between the reactants and products.
How is Hf related to the H of a reaction?
The Hreaction is the difference between Hf, products and Hf, reactants
What is the difference between the bond enthalpy of the reactants and the bond enthalpy of the products in a chemical reaction?
The difference between the bond enthalpy of the reactants and the bond enthalpy of the products in a chemical reaction represents the energy change that occurs during the reaction. If the bond enthalpy of the products is lower than that of the reactants, it indicates that energy is released during the reaction, making it exothermic. Conversely, if the bond enthalpy of the products is higher than that of the reactants, it indicates that energy is absorbed during the reaction, making it endothermic.
Look at the chemical reaction How does the chemical energy of the reactants compare to the chemical energy of the products?
In a chemical reaction, the chemical energy of the reactants is typically higher than that of the products. This is because energy is needed to break the bonds in the reactants to form new bonds in the products. The difference between the energy of the reactants and the products is often released or absorbed as heat.
What does a potential energy graph in chemistry reveal about the relationship between reactants and products in a chemical reaction?
A potential energy graph in chemistry shows the energy changes that occur during a chemical reaction. It reveals how the energy of the reactants compares to the energy of the products. The graph can indicate whether the reaction is exothermic (releasing energy) or endothermic (absorbing energy), and the overall energy difference between the reactants and products.
What statement describes the potential energy diagram of an exothermic reaction?
The difference in potential energy between the reactants and products.
What describes the reactants and products involved in a reaction?
Reactants are the substances that are consumed or used up in a chemical reaction to form products. Products are the new substances that are formed as a result of the reaction between the reactants.
How is Hf related to the H of a reaction?
The Hreaction is the difference between Hf, products and Hf, reactants
What is the difference between a reversible reaction and a reaction that goes to completion?
The reactions in which the products can recombine to form reactants are called reversible reactions. These reactions never go to completion. They are represented by a double arrow between reactants and products.
Look at the chemical reaction How does the chemical energy of the reactants compare to the chemical energy of the products?

This is because energy is needed to break the bonds in the reactants to form new bonds in the products. The difference between the energy of the reactants and the products is often released or absorbed as heat.

Conversely, if the bond enthalpy of the products is higher than that of the reactants, it indicates that energy is absorbed during the reaction, making it endothermic.
In an exothermic reaction the difference between the chemical energy of the reactants and the chemical energy of the products equals?
The amount of heat given off by the reaction
What is the arrow between the reactants and products?
The arrow between the reactants and products in a chemical equation represents the direction of the chemical reaction. It indicates that the reactants are being transformed into the products.
How is the H related to the H of a reaction?
The h reaction is the difference between Hf products and Hf reactants - apex
What kind of properties has the elements for when you combine new sustances?
It is a big difference between the properties of reactants and products; an element is not a compound.
What does the difference in potential energy between the reactants and products represent?
It represents the change in enthalpy for the reaction.
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.
