Study the graph.
The graph shows energy over the course of a chemical reaction. At the start of the reaction, the reactants have a medium amount of energy. Then the level of energy peaks, and starts to quickly decline. The product of the reaction has a low amount of energy.
Based on the information in the graph, choose the statement that best describes the reaction it depicts.
A. The reaction absorbs energy.
B. The reaction releases energy.
C. The reaction fails to proceed because of insufficient energy.
D. The reaction fails to proceed because it does not involve an energy change.

Option B which is that The reaction releases energy is the correct statement.
- As it is given in the question that the energy of the reactant is medium whereas the energy of the product is low, which means that the formation of the product is not brought by the expenditure of energy instead energy will be released in the form of heat and light probably.
- Such reactions are generally exothermic and require little to no expenditure of heat. A catalyst can speed up such reactions and can also lower the activation energy of the reactants.
- The possibility of such reactions being spontaneous thermodynamically is also quite good since the complete assurance can only be defined based on Gibbs free energy which is another and most important thermodynamic parameter to predict the feasibility of the reaction.
