We present a complete theory of vibrational strong coupling (VSC) modified rate constants in polariton chemistry when single molecule to an optical cavity. The analytic expression exhibits sharp resonance behavior, where the maximum constant is reached cavity frequency matches vibration frequency. also explains why VSC modification closely resembles spectra outside This expression, together with our previous under lossy regime, provides mechanistic picture for VSC-enhanced simple double well reactive model system. Our suggests that there will be turnover as one changes lifetime, and first scale quadratically respect light-matter strength then saturate. agree numerically exact hierarchical equations motion (HEOM) simulations all explored regimes. Further, we discussed temperature dependence VSC-modified constants, agrees numerical simulations. Finally, condition at normal incidence considering in-plane momentum inside Fabry-P\'erot
