Science / Chemistry / Diffusion Rate: The number of randomly moving molecules that pass through a unit area per second. Diffusion rates are fastest when a large concentration difference exists on either side of the unit area. Diffusion rates increase with temperature, and decrease with increasing pressure, molecular weight, and molecular size.
Rate Noun Synonyms: rank, grade, class, classify, evaluate, estimate, calculate, compute, count, reckon, judge, gauge, assess, appraise, measure
