In chemistry, a reaction quotient Qr is a function of the activities or concentrations of the chemical species involved in a chemical reaction.

The chemical defense of this species was first studied by Thomas Eisner and Jerrold Meinwald (two scientists at Cornell University who helped found the field of chemical ecology).

In chemical thermodynamics, activity (symbol a ) is a measure of the effective concentration of a species in a mixture, in the sense that the species' chemical potential depends on the activity of a real solution in the same way that it would depend on concentration for an ideal solution.

An elementary reaction is a chemical reaction in which one or more of the chemical species react directly to form products in a single reaction step and with a single transition state.

They communicate with plants of other species and they communicate with animals by producing chemical volatiles, for example, during the pollination.

Hyperspectral imaging has been used as a tool to monitor the plant stress induced in plants that naturally bio accumulate certain chemical species.

The reaction can be represented with the chemical equation 2 As 3 S As2S3Upon heating in a vacuum, polymeric As2S3 cracks to give a mixture of molecular species, including molecular As4S6.
