In an effect whose name contains this word, reactions involving heavier isotopes like deuterium proceed relatively slowly. One result of a theory whose name contains this word is that ideal gases obey a Maxwell-Boltzmann velocity distribution. A substance like diamond has this kind of stability if a high energy barrier prevents it from reacting. This kind of stability contrasts with thermodynamic stability. The field of this name studies things like pseudo-first-order rate laws and reaction rates. For 10 points, name this field which studies the rate at which reactions occur, and which shares its name with the type of energy possessed by a bo
