Relative change of the reaction rate \(k({g}_{{\rm{R}}})/k({g}_{{\rm{R}}}\mathrm{=0)}\) as a function of the collective Rabi frequency (or coupling strength) \({g}_{{\rm{R}}}\sqrt{N}\) (normalized by the vibrational frequency ωR) for the case of gP = gR in a system of N = 2 identical molecules (black) and in the single-molecule system (red).
