K for Overall Reaction

Concept #1: Calculating Keq of the Overall Reaction.

Multiplying all the new Keq values gives us Keq of the overall reaction.

Practice: Calculate Kc for: C(s) + ½ O2(g) + H2(g) ⇌ ½ CH3OH(g) + ½ CO(g)  Kc = ?

Given the following reactions:
4 C(s) + 2 O2(g) ⇌ 4 CO(g)                               Kp = 2.11 x 1043
CH3OH(g) + H2O(g) ⇌ CO2(g) + 3 H2(g)          Kp = 7.17 x 10–2
CO(g) + H2O(g) ⇌ CO2(g) + H2(g)                     Kp = 2.00 x 103
