Nuclear & RadiochemistryRadioactivity
The spontaneous emission of particles or electromagnetic radiation from unstable atomic nuclei.
Chemical Kinetics & CatalysisRate-Determining Step
The slowest step in a reaction mechanism, which limits the overall rate.
Chemical Kinetics & CatalysisReaction Intermediate
A species produced in one step of a mechanism and consumed in a later one, so it does not appear in the overall equation.
