Answer
This statement can be evaluated based on the graph of reaction P. If the energy level of the products is indeed higher than that of the reactants, it indicates that the reaction absorbs energy, thus categorizing it as endothermic.
Step 2
B. activation energy of reaction M is greater than that of reaction P.

Answer
To determine the activation energy from the graphs, we can identify the difference in energy levels between the reactants and the peak of the reaction. If reaction M has a higher peak than reaction P starting from the same reactant energy level, then this statement holds true.
Step 3
C. both graphs M and P represent endothermic reactions.

Answer
This can be concluded if the energy of the products in both reactions is higher than that of the reactants. If one graph depicts an exothermic reaction where products are lower in energy than reactants, this statement is false.
Step 4
D. energy is released in reaction P only.

Answer
This statement suggests that reaction P is the only one that releases energy. If the graph of reaction P shows products at a lower energy level than the reactants, this statement would be true. Reaction M would then be endothermic.
