Question

This graph shows how the potential energy of a reaction system changes
over time. Which statement is true for this system
A. The potential energy of the reactants is greater than the potential
energy of the products.
B. The height of the curve at point A represents the activation energy.
C. The height of the curve at point B represents the activation energy.
D. The potential energy of the products is greater than the potential
energy of the reactants.

Answer 1

Answer:

Answer is C since activation energy is needed in a reaction

Answer 2

Potential energy is the energy present in the reactions. The potential energy of the reactant in the graph is more than that of the product. Thus, option A is accurate.

What is potential energy?

Potential energy is the energy of the reaction that results in the formation of products. The potential energy is reduced in the exothermic reactions as energy is released along with the products.

The bonds present in the reactants in the reaction mixture split in the presence of the activation energy to release energy and form the product.

Therefore, option A. the graph shows the greater potential energy of the reactant.
