Reaction Barriers & Energy Dissipation

Primes about the energetic barriers and flows governing whether a transformation proceeds: thresholds that gate a transition (activation energy, nucleation), facilitators that lower a barrier without being consumed (catalysis), and irreversible energy exchange with the surroundings (dissipation, environmental coupling strength).

5 primes in this family — primes that sit near one another in abstraction space (k-means over structural-signature embeddings). Each is shown with its short description.

• Activation Energy — The minimum input that must be supplied to push a thermodynamically favorable but stalled process past a barrier before momentum carries it to completion.
• Catalysis — A facilitator lowers the barrier of a permitted-but-slow transformation on a specific pathway and returns unconsumed each cycle, so a small quantity transforms a large substrate over many turnovers.
• Dissipation — Irreversible conversion of organized energy or order into thermalized, unrecoverable form across many degrees of freedom.
• Environmental Coupling Strength — Rate of energy, information, or material exchange across boundary.
• Nucleation — A metastable system cannot transition globally because a new phase's surface cost exceeds its volume benefit at small size; transition begins only when a seed crosses the critical-nucleus threshold and then grows.
