Molecular abundances computed for hot (T_eq = 1000 K) or warm (T_eq = 700 K), and very (Z_⊙× 350) or moderately (Z_⊙× 5) enriched atmospheres, using the chemical kinetics code of Venot et al. (2012). The colored lines denote the disequilibrium abundances for the main molecules in the planetaryatmosphere. The gray lines indicate the chemical equilibrium state. A constant K_zz = 10¹⁰ cm² s⁻¹ and C/O = 0.3 were adopted.
