Earlier [V. P. Lesnikov, Ukr. J. Phys. 64, 126 (2019)] it was pointed out that for thermal hydrodynamic fluctuations in open hydrodynamic steady states (OHSS) the determining factor for derivation of reciprocal relations is not the principle of microscopic reversibility, but the presence or absence of a flux. In the present work this idea is applied to open chemical steady states (OCSS), where chemical oscillations are possible. The behavior of concentration fluctuations when there are no macroscopic oscillations yet is considered. The reciprocal relations for such OCSS are found.

Key words: open chemical steady state (OCSS), chemical oscillators, concentration fluctuations, reciprocal relations.
