Effective H₂ formation rate. Left panel: two H₂ formation models for a molecular cloud of n_H = 10⁴ cm⁻³ and assuming T_d = T_g (MC-ANALYTIC, MC-PHYS and MC-PHYS-CHEM-PAH). We also show the effect of competition diffusion-reaction rates (no compet. MC-PHYS-CHEM-PAH). Right panel: H₂ formation model MC-PHYS-CHEM-PAH when T_d and T_g can be different.
