Morphology

reactivity = reactive (transparent) = react + ive + ity

Formed regularly from 'react' -> 'reactive' -> 'reactivity'; denotes the property of being reactive, which is directly predictable from the base.

Etymology

Reactivity comes from the parts re- meaning 'back' or 'again' and act meaning 'do', with -ivity making a word for 'quality'. So in chemistry reactivity is the 'quality' of how easily a substance 'responds' and changes when it meets another chemical.
