Example #1
At 448 C the equilibrium constant Kc for the reaction is 50.5.
H2 (g) + I2 (g) ⇌ 2HI (g)
Predict in which direction the reaction proceeds to reach equilibrium if we start with 2.0 102 mol of HI, 1.0
102 mol of H2 , and 3.0 102 of I2 in a 2.00-L container.
Example #2
For the reaction: N2 (g) + 3H2 (g) ⇌ 2NH3 (g), Kc = 0.50 at 500°C.
If [N2] = 0.5 M, [H2] = 0.6 M, and [NH3] = 0.2 M, calculate Qc and predict the direction of the shift.
