This study guide covers thermodynamic favorability and spontaneity of reactions. Key concepts include enthalpy (ΔH°), entropy (ΔS°), and Gibbs Free Energy (ΔG°). It explains how to calculate ΔG° using the formula ΔG° = ΔH° - TΔS° and standard free energies of formation. The guide also discusses conditions influencing spontaneity and distinguishes between entropy-driven and enthalpy-driven reactions, including practice problems and exam tips.

Question 1 of 9
A spontaneous reaction is best described as one that:
Requires continuous external energy input
Happens on its own without continuous external assistance. ✅
Results in a decrease in the system's entropy
Always absorbs heat from the surroundings
