Particle production in central Pb-Pb collisions at the CERN Large Hadron Collider is discussed in the context of the statistical model. Predictions of various particle ratios are presented with the corresponding choice of model parameters made according to the systematics extracted from heavy-ion collisions at lower energies. The sensitivities of several ratios to the temperature and baryon chemical potential are studied in detail, and some of them, which are particularly appropriate to determining the chemical freeze-out point experimentally, are indicated. We show that the p/p ratio is most suitable for determining the baryon chemical potential, while the {omega}{sup -}/K{sup -} and {omega}{sup -}/{pi}{sup -} ratios are best for determining the temperature at chemical freeze-out.
