Answer 1

In physical chemistry, extent of reaction is a quantity that measures the extent in which the reaction proceeds. It is usually denoted by the Greek letter ξ. The extent of a reaction has units of amount (moles). It was introduced by the Belgian scientist Théophile de Donder.

Suppose an infinitesimal amount dξ of the reactant A changes into B. The change of the amount of A can be represented by the equation dnA = – dξ and the change of B is dnB = dξ. The extent of a reaction is defined as zero at the beginning of the reaction.
