p. 905. Reactivitylocked

  • William H. Brock


By the mid-19th century many different kinds of chemical change had been recognized and systematized in textbooks. It became the task of physical chemists to explain these different transformations in terms of exchanges between atoms and molecules powered by energy changes and the shifts in equilibrium that underlay all reactivity. Physical chemists found ways of expressing chemical change in mathematical terms and so brought generalization and systematization to chemical practice. ‘Reactivity’ considers the conditions for chemical equilibria and the mechanisms involved in chemical reactions by discussing concepts such as thermodynamics, periodicity, spectroscopy, ideal gases, Boyle’s law, electrolysis, ionic theory, kinetics, and inert gases.
