(a) At 800 K the equilibrium constant for I2(g) 2 I(g) is Kc = 3.1 × 10-5. If an equilibrium mixture in a 10.0-L vessel contains 2.67 × 10-2 g of I(g), how many grams of I2 are in the mixture?
(b) For 2 SO2(g) + O2(g) 2 SO3(g), Kp = 3.0 × 104 at 700 K. In a 2.00-L vessel the equilibrium mixture contains 1.17 g of SO3 and 0.105 g of O2. How many grams of SO2 are in the vessel?
