High rate constant
WebAug 26, 2010 · In physics, speed is already the rate of distance over time, otherwise known as velocity. Rate of speed is velocity over time, otherwise known as acceleration. By saying high rate of speed they would be implying picking up more speed. Is there a social reason for using high rate of speed rather than high speed? synonyms colloquialisms WebRate constants for association reactions (Table 2) of the type A + B ↔ [AB]* AB can be pressure dependent.
