Equilibrium chemistry refers to the study of chemical reactions at a state of balance, where the rates of forward and reverse reactions are equal.
Full definition
Thus Lovelock argued, «if life has merely a passive role in cycling the gases of the air, then the concentrations will be set
by equilibrium chemistry; in fact they most certainly are not.»
The researchers developed atmospheric models of
the equilibrium chemistry for a brown dwarf at 250 degrees Kelvin and calculated the resulting spectra under different assumptions, including cloudy and cloud - free models.
