MCAT General Chemistry (Princeton Review) Questions and Answers | Latest Update | 2024/2025 | Already Passed What is the role of a Lewis acid and a Lewis base in a chemical reaction? A Lewis acid is an electron pair acceptor, while a Lewis base is an electron pair donor. They interact to form a coordinate covalent bond where the base donates an electron pair to the acid. How does the concept of bond enthalpy relate to the strength of a chemical bond? Bond enthalpy (or bond dissoci...

MCAT General Chemistry | Latest Update | 2024/2025 | Already Passed What is the role of the conjugate base in an acid-base reaction, and how does it influence the reaction equilibrium? The conjugate base is formed when an acid donates a proton. It influences the reaction equilibrium by interacting with the acid, shifting the equilibrium based on the relative strengths of the acid and its conjugate base. How does the presence of a common ion affect the solubility of a salt in a solu...

Understand the concepts of enthalpy (H), entropy (S), free energy (G), and free energy change (ΔG). - ANSWER-Δ-G = favorable/spontaneous (exergonic) Δ+G = not favorable/non-spontaneous (endergonic) ΔG does NOT say anything about rate What is meant by favorability/spontaneity in relation to a chemical reaction? - ANSWER-This refers to what is going to be more likely to happen/form in a chemical reaction. Although entropy is favored by the universe, it isn't seen as often. Every reac...
