1. When BaCO3 is first mixed with K3PO4 their concentrations are measured at: [BaCO3] = 0.968M and [K3PO4] = 0.745M. The reaction is allowed to progress until equilibrium is reached. At equilibrium [K₂CO3] = 0.804M. Calculate Keq. 3BaCO3(aq) + 2K3PO4 (aq) <-> Ba3(PO4)2 (aq) + 3K₂CO3(aq) 2. Hydrogen and iodine gases react to form hydrogen iodide gas. If 12.00 mol of H2 and 12.00 mol of I2 are placed in a 3.00 L vessel and allowed to come to equilibrium at 250°C calculate the equilibrium concentrations of all species. The Keq for the reaction is 4.00 at 250°C. H2(g) + I2(g) <-> HI(g) 3. At a certain temperature, Keq for the reaction H2O (g) + CO (g) <-> CO2 (g)+H2 (g) is found to be 0.667. If the initial concentrations of each of the four substances is 0.25M, calculate the equilibrium concentrations of all substances.
