Reactivity is a somewhat vague concept in chemistry. It appears to embody both thermodynamic factors and kinetic factors (i.e., whether or not a substance reacts, and how fast it reacts).
Reactivity may refer to: Reactivity (chemistry) , the rate at which a chemical substance tends to undergo a chemical reaction Reactive programming , a property of an execution model whereby changes are automatically propagated through a dataflow network
In chemistry, a reactivity series (or reactivity series of elements) is an empirical, calculated, and structurally analytical progression ...
Reactivity is a phenomenon that occurs when individuals alter their performance or behavior due to the awareness that they are being observed. [1] The change may be positive or negative, and depends on the situation. It is a significant threat to a research study's external validity and is typically controlled for using blind experiment designs.
The reactivity ratio for each propagating chain end is defined as the ratio of the rate constant for addition of a monomer of the species already at the chain end to the rate constant for addition of the other monomer.
The reactivity of a chemical substance is a description of how it might react across a variety of potential chemical systems and, for a given system, how fast such a reaction could proceed. Chemical substances or states can persist indefinitely even though they are not in their lowest energy state if they experience metastability - a state ...

By definition, reactivity of zero dollars is just barely on the edge of criticality using both prompt and delayed neutrons. A reactivity less than zero dollars is subcritical; the power level will decrease exponentially and a sustained chain reaction will not occur. One dollar is defined as the threshold between delayed and prompt criticality.
