Problem: For the reaction shown here:2H2O(g)  ⇌ 2H2(g)+O2(g)the equilibrium concentrations were found to be:[H2O]=0.250 M[H2]=0.560 M[O2]=0.800 MWhat is the equilibrium constant for this reaction?Keq =?  

FREE Expert Solution

We’re asked to determine the equilibrium constant, Keq for the given reaction:

2H2O(g)  2H2 (g) + O2 (g)

Recall that the equilibrium constant is the ratio of the products and reactants

We use Kp when dealing with pressure and Kc when dealing with concentration:

Kp=PproductsPreactants     Kc=[products][reactants]

Note that solid and liquid compounds are ignored in the equilibrium expression.
