@X@user.full_name@X@ @GMU: Initially there were equilibrium concentrations of 0.1859 M A, 0.3333 M B, and 0.1859 M C (see reaction below). The concentration of C was suddenly increased to 11.73 M. What was the approximate concentration of each after equilibrium had been re-established?5A → 3 B +3 C Kc = 1.073

@X@user.full_name@X@ @GMU: It has been suggested that carbonyl chloride forms by the mechanism below. What is the molecularity of the rate limiting step? (1) Cl2(g) → 2 Cl(g) Fast, equilibrium (2) Cl(g) + CO(g) → COCl(g) Fast, equilibrium (3) COCl(g) + Cl2(g) → COCl2(g) +Cl(g) Slow

@X@user.full_name@X@ @GMU: A mixture containing an initial concentration of 0.1930 M for H2 and 0.1430 M for I2 is allowed to come to equilibrium (see reaction below). What must be the equilibrium concentration of HI?H2(g) + I2(g) → 2HI(g) Kc = 48.7000

@X@user.full_name@X@ @GMU: The following data was obtained by the method of initial rates. What is the rate law for the reaction of A with B to produce product? [A]o [B]o Rate, M/s 0.273 0.347 7.28e-4 0.481 0.347 7.28e-4 0.273 0.612 1.70e-3

@X@user.full_name@X@ @GMU: What is the solubility in g/L of CH2CHCl at a partial pressure of 526.5 torr, if the solubility at a partial pressure of 427.7 torr is 3.201 g/L?

@X@user.full_name@X@ @GMU: When 0.1901 g of aspirin was dissolved in 100.5 mL of water, the osmotic pressure at 10.92°C was 0.2498 atm. What is the formula mass of this compound?

@X@user.full_name@X@ @GMU: What is the solubility in g/L of O2 at a partial pressure of 653.9 torr, if the solubility at a partial pressure of 487.7 torr is 0.02833 g/L?

John Schreifels @GMU: When 7.237 g of lysine was dissolved in 109.9 g of benzene, the freezing point was 276.3 K. What is the formula mass of this compound? The freezing point depression constant for benzene is 5.12 (°C*kg)/mol. The melting point and boiling points are 5.50°C and 80.10°C, respectively.

@X@user.full_name@X@ @GMU: A mixture containing an initial concentration of 0.1506 M for H2 and 0.1223 M for Br2 is allowed to come to equilibrium (see reaction below). What must be the equilibrium concentration of HBr?H2(g) + Br2(g) → 2HBr(g) Kc = 1.42e3
