An equilibrium mixture of PC, (g), PCl,(g), and CL, (g) has partial pressures of 217.0 Torr, 13.2 Torr, and 13.2 Torr, respectively. A quantity of CL,(g) is injected into the mixture, and the total pressure jumps to 263.0 Torr at the moment of mixing. The system then re-cquilibrates. The chemical equation for this reaction is PCI, (g) + CL,(g) PCI, (g) Calculate the new partial pressures, P, after equilibrium is reestablished.

When 0.200 mol of CaCO,(s) and 0.300 mol of CaO(s) are placed in an evacuated, sealed 10.0-L container and heated to 385 K, PCO, = 0.220 atm after equilibrium is established. 2 CACO,(s) = CaO(s) + CO,(g) Additional CO,(g) is pumped into the container to raise the pressure to 0.470 atm. After equilibrium is re-established, what is the total mass (in g) of CaCO, in the container?
