Gibbs Free Energy Spontaneity Criterion
吉布斯自由能判据与反应自发性
Theoretical Identity Description:
Determines the thermodynamic spontaneity of a chemical reaction at constant T and P. Spontaneous when ΔG < 0, at equilibrium when ΔG = 0.
Rigorous Derivation Tree
Foundational identity statement defined under standard mathematical conditions.
Targeted algebraic evaluation and parameter substitution.
CSCA Exam Triggers & Traps
Use for predicting spontaneous temperature ranges for endothermic reactions with gas production.
Thermodynamic spontaneity (ΔG < 0) means the reaction is energetically feasible, but does NOT guarantee a fast kinetic rate.
