Answer to Question #205289 in General Chemistry for Cassandra

Question #205289

When 1.50 mol of CO2 and 1.50 mol H2 are placed in a 3.00-L container at 395ºC, the following reaction occurs: CO2(g) + H2(g) ↔ CO(g) + H2O(g).


If Kc = 0.802, what are the concentrations of each substance in the equilibrium mixture?

The balanced chemical equation:

CO2(g) + H2(g) ↔ CO(g) + H2O(g)

The equilibrium expression for the reaction system



[CO] = [H2O] = x = 0.945 M

[CO2] = [H2] = 2.00 - 0.945 = 1.055 M = 1.06 M


Answer:


[CO] = [H2O] = 0.945 M;

[CO2] = [H2] = 1.06 M.
