From theCambridge English Corpus Other processes such aschemicalreactionand heat or mass transfer have similar dependencies on the residence time distribution. From theCambridge English Corpus Indeed, spatial and temporal organization is a fundamental property of living systems and of great interest forchemicalreactionsystems in general. From theCambridge English Corpus Of course, contact with another molecule does not yet necessarily trigger achemicalreactionbetween the two.
