Question

For the energy diagram of the chemical reaction depicted here, which of the following is the best conclusion?

the reaction is endothermic

the reaction is exothermic

the activation energy is never achieved if products form

the activation energy is the lowest energy level

Answer 1

Answer: B The reaction is exothermic

Answer 2

From the energy diagram of the chemical reaction depicted, the best conclusion is the reaction is exothermic.

What is an Exothermic reaction?

This is the type of reaction which involves release of energy with the overall standard enthalpy change ΔH⚬ being negative.

This is why the energy of the reactant is greater than that of the product thereby making option B the most appropriate choice.
