2. A Question-by-Question Analysis of the 2015 AP Chemistry Free Response
The 2015 AP Chemistry free-response section consisted of seven questions, each testing different aspects of the course content. While the specific questions are not included here (due to copyright restrictions and the need for readers to consult the original exam), a generalized analysis of the question types follows:
Question 1 (Equilibrium): This question typically involved a problem dealing with equilibrium constants, Le Chatelier's principle, and calculations involving changes in reaction conditions. The 2015 version likely probed students' understanding of equilibrium shifts and the manipulation of equilibrium expressions.
Question 2 (Acids and Bases): This section often focused on acid-base titrations, pH calculations, buffer solutions, and the relationship between Ka and Kb. The 2015 question likely tested students’ ability to perform calculations and interpret titration curves.
Question 3 (Thermodynamics): This frequently involved calculations of enthalpy, entropy, and Gibbs free energy changes, and their relationship to spontaneity. Understanding Hess's Law and the application of thermodynamic principles to chemical reactions would have been crucial in the 2015 question.
Question 4 (Kinetics): This section typically explored reaction rates, rate laws, activation energy, and reaction mechanisms. Students likely had to interpret experimental data or apply integrated rate laws in the 2015 FRQ.
Question 5 (Descriptive Chemistry): This question focused on identifying properties and trends within the periodic table, predicting reactivity based on periodic trends, and describing the properties of various compounds.
Question 6 (Organic Chemistry): This section tested students’ understanding of basic organic functional groups, nomenclature, and reaction mechanisms.
Question 7 (Electrochemistry): This often involved redox reactions, electrochemical cells, and the Nernst equation. The 2015 question likely required students to understand cell potential, electron transfer, and the relationship between Gibbs free energy and cell potential.
Each of these questions in the 2015 AP Chemistry free response section demanded a deep understanding of fundamental principles and the ability to apply those principles to solve complex problems. The questions emphasized problem-solving skills and the ability to communicate scientific reasoning effectively.

| 2015 ap chemistry free response: Redox and Nitrosative Signaling in Cardiovascular System: from Physiological Response to Disease Mariarosaria Santillo, Pasquale Pagliaro, 2019-01-22 The role of ROS/RNS signaling in cardiovascular functions and diseases is increasingly emerging in the last decades. The involvement of ROS/RNS in the control of a large number of cardiovascular functions like the regulation of the vascular tone, the control of blood pressure or myocyte excitation-contraction coupling and force development has been broadly investigated and in part clarified. On the other hand, many efforts have been focused in clarifying the redox mechanisms involved in cardiovascular diseases like ischemia/reperfusion injury, diabetes-associated cardiovascular dysfunctions, atherosclerosis or hypertension, just to mention the major ones. However, in most cases the two levels of investigation remain separate and not interlaced, failing in the attempt to provide a unified vision of the pathophysiologic mechanisms of cardiovascular diseases. The major aim of the Research Topic has been to collect original papers and review articles dealing with the issue from basic to translation research point of views. The topic includes contributions that highlight different interesting aspects of cardiovascular biology with an integrated approach useful for the development of new ideas and advancements in the field of redox signaling in the control of normal cardiovascular functions and their disruption in diseases. |
| 2015 ap chemistry free response: The Nature of the Mechanical Bond Carson J. Bruns, J. Fraser Stoddart, 2016-11-07 “The story is told by THE inventor-pioneer-master in the field and is accompanied by amazing illustrations… [it] will become an absolute reference and a best seller in chemistry!” Alberto Credi “… the great opus on the mechanical bond. A most impressive undertaking!” Jean-Marie Lehn Congratulations to co-author J. Fraser Stoddart, a 2016 Nobel Laureate in Chemistry. In molecules, the mechanical bond is not shared between atoms—it is a bond that arises when molecular entities become entangled in space. Just as supermolecules are held together by supramolecular interactions, mechanomolecules, such as catenanes and rotaxanes, are maintained by mechanical bonds. This emergent bond endows mechanomolecules with a whole suite of novel properties relating to both form and function. They hold unlimited promise for countless applications, ranging from their presence in molecular devices and electronics to their involvement in remarkably advanced functional materials. The Nature of the Mechanical Bond is a comprehensive review of much of the contemporary literature on the mechanical bond, accessible to newcomers and veterans alike. Topics covered include: Supramolecular, covalent, and statistical approaches to the formation of entanglements that underpin mechanical bonds in molecules and macromolecules Kinetically and thermodynamically controlled strategies for synthesizing mechanomolecules Chemical topology, molecular architectures, polymers, crystals, and materials with mechanical bonds The stereochemistry of the mechanical bond (mechanostereochemistry), including the novel types of dynamic and static isomerism and chirality that emerge in mechanomolecules Artificial molecular switches and machines based on the large-amplitude translational and rotational motions expressed by suitably designed catenanes and rotaxanes. This contemporary and highly interdisciplinary field is summarized in a visually appealing, image-driven format, with more than 800 illustrations covering both fundamental and applied research. The Nature of the Mechanical Bond is a must-read for everyone, from students to experienced researchers, with an interest in chemistry’s latest and most non-canonical bond. Read the Preface |
