Worked Solution & Example Answer:The following graphs depict two different reactions - VCE - SSCE Biology - Question 23 - 2011 - Paper 1
Step 1
A. in reaction P, the energy level of the products is greater than that of the reactants.
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.
