In an exothermic reaction, the enthalpy change is negative. Which of the following is also true for an exothermic reaction?

The products have a lower potential energy than the reactants.

The reactants have a lower potential energy than the products.

The potential energy of both the reactants and products is the same.

The potential energy decreases, and then increases sharply at the end of the reaction.

And to answer your question i dont no if ur right.. Im just hoping u are becasue im totally lost with this hw

anonymous · Answer

For an exothermic reaction, what would the potential energy diagram most likely look like?

 a curve with a negative slope indicating that the activation energy has a negative value

 a curve indicating that the amount of energy absorbed during the reaction is high

 a curve indicating that the potential energy of the reactants is higher than the products

 a curve indicating that the potential energy of the products is higher than the reactants
