Question

What does a positive AH look like on a potential energy diagram?

A. The activation energy of the reactants is less than the activation
energy of the products.
B. The potential energy of the products is equal to the potential
energy of the reactants.
C. The potential energy of the products is greater than the potential
energy of the reactants.
D. The potential energy of the reactants is greater than the potential
energy of the products.

Answer 2

Answer: In an endothermic reaction for whom the value of
`\Delta H` is positive has potential energy of the products greater than the potential energy of the reactants.

Step-by-step explanation:

A chemical reaction in which heat energy is absorbed is called an endothermic reaction. For an endothermic reaction the value of
`\Delta H` is positive.

A chemical reaction in which heat energy is released is called an exothermic reaction. For an exothermic reaction the value of
`\Delta H` is negative.

In an endothermic reaction, heat energy is absorbed by the reactant molecules due to which the energy of products tend to increase. As potential energy is the energy acquired by a substance due to its position.

Therefore, we can conclude that in an endothermic reaction for whom the value of
`\Delta H` is positive has potential energy of the products greater than the potential energy of the reactants.
