Rate of Radioactive Decay definitions Flashcards

A process following a first-order rate law, characterized by a decrease in radioactive nuclei over time.

A kinetic model where the rate of reaction is directly proportional to the concentration of one reactant.

A proportionality factor in the radioactive decay equation, indicating the rate of decay over time.

The logarithm to the base e, used in the integrated rate law to express concentration changes.

An equation relating the concentration of reactants to time, used to describe radioactive decay.

The amount of a substance in a given volume, which in radioactive decay can refer to disintegrations per second.

In the context of decay, it represents the negative decay constant in a plot of ln(N) versus time.

A variable in the decay equation, representing the duration over which decay is measured.

A unit of measure for radioactive decay, indicating the number of nuclei decaying each second.

A mathematical representation, y=mx+b, used to describe the linear relationship in decay plots.

A visual representation of data, such as ln(N) versus time, showing the decay process.

The vertical axis in a graph, representing ln(N) in the context of radioactive decay.

The horizontal axis in a graph, representing time in the context of radioactive decay.

The starting amount of radioactive nuclei before decay begins, denoted as N0.

The remaining amount of radioactive nuclei after a period of decay, denoted as N.
