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 else can I help you with?
Which statement describes a reaction where the amount of remaining or the concentration of reactant is less each minute?
Probable you think to the reaction rate.
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 statement describes a reaction at 298 K if H 31 kJmol S 0.093 kJ(molK)?
It is not spontaneous.
Which is the untrue statement concerning the diels alder reaction?
The untrue statement concerning the Diels-Alder reaction is that it does not involve the formation of a cyclic compound.
Is a road flare exthermic or endothermic?
Exothermic, because it releases heat as a form of energy.
What statement best describes the potential energy diagram of an endothermic reaction?
The potential energy of the products is greater than the potential energy of the reactants.

What heat transfer associated with a chemical reaction or pharse changs as either exthermic or endothermic?
to see your mom.
What statement describes the potential energy diagram of an endothermic reaction?
The potential energy of the products is greater than the potential energy of the reactants.

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.
Which statement best describes the reaction of Northerners to the Kansas-Nebraska Act?
They strongly disapproved of the act.
What statement best describes the role of gametocytes in the spread of malaria?
they cause a chemical reaction that alters human scent
What statement describes a reaction at 298 K if H 31 kJmol S 0.093 kJ(molK)?
It is not spontaneous.
What statement describes the potential energy diagram of an exothermic reaction?
The difference in potential energy between the reactants and products.
What statement correctly describes an endothermic chemical reaction?
An endothermic chemical reaction absorbs heat from its surroundings, causing a decrease in temperature. This type of reaction typically feels cold to the touch and requires an external heat source to proceed.
Which statement describes the public's reaction to early labor unions?
Many people distrusted unions because some were organized by socialists.
