Calculating Equilibrium Concentrations from Initial Concentrations
A 1.000-L flask is filled with 1.000 mol of H2(g) and 2.000 mol of I2(g) at 448 °C. The value of the equilibrium constant Kc for the reaction
H2(g) + l2(g) ⇌ 2 Hl(g)
at 448 °C is 50.5. What are the equilibrium concentrations of H2, I2, and HI in moles per liter?
For the equilibrium Br2(g) + Cl2(g) ⇌ 2 BrCl(g), the equilibrium constant Kp is 7.0 at 400 K.
If a cylinder is charged with BrCI(g) at an initial pressure of 1.00 atm and the system is allowed to come to equilibrium what is the final (equilibrium) pressure of BrCI?
(a) 0.57 atm. (b) 0.22 atm, (c) 0.45 atm, (d) 0.15 atm, (e) 0.31 atm.
